Including 7 traffickers in Contra Costa County; Contra Costa DA’s Office, Pittsburg PD participate
By Lt. Joshua Singleton, Task Force Commander, Human Trafficking Task Force, Santa Clara District Attorney’s Office
Days after the Super Bowl, the Santa Clara County District Attorney’s Human Trafficking Task Force reported its own statistics: numbers that showed enhanced investigations resulted in the arrests of 29 traffickers and the recovery of 73 sex trafficking victims, including 10 minors. One of the victims, who was being trafficked in Oakland, was 12 years old.
Law enforcement operations were held throughout 11 Bay Area counties during the lead up to one of the world’s biggest sporting events. Similar enforcement is being prepared for the deluge of fans coming to see the 2026 FIFA World Cup soccer tournament games at Levi’s Stadium between June 13 and July 1.
District Attorney Jeff Rosen said: “Beyond football, the Super Bowl was a triumph of Bay Area law enforcement planning, organization, cooperation, and safety. Human trafficking is not a game, it’s a tragedy. However, our team was very successful. Close to 70 agencies effectively discouraged traffickers from exploiting the game and victims. For traffickers that still came to the game from all over the world with bad intentions, many ended up behind bars.”
The HTTF helped organize the efforts of 67 law enforcement agencies from Sacramento to Monterey.
For two weeks before the Big Game, the Task Force set up a command center in Sunnyvale populated with more than 20 analysts from various agencies, such as the Santa Clara County Sheriff’s Office, the DA’s Crime Strategies Unit, the Contra Costa District Attorney’s Office, Pittsburg Police Department, federal agencies, and partners from community-based organizations such as In Our Backyard, and the National Center for Missing and Exploited Children. The analysts worked on tips in real time and worked alongside agents in the field to do investigations and make arrests. Operations that often take weeks took minutes in the enhanced Human Trafficking Tactical Operations Center.
Launching almost 40 operations, investigators recovered 20 victims from San Mateo County alone. Seven traffickers were arrested in Contra Costa; six in Monterey and Solano counties. In Santa Clara County, seven victims were recovered, two traffickers arrested and a firearm was seized.

Martinez, CA – The Contra Costa County District Attorney’s Office (CCCDAO) issued a public report on a use of force incident in Antioch that resulted in the shooting death of David Wali Bahrami on June 30th, 2025, and finds the officers acted in reasonable self-defense/defense of others.
When a law enforcement officer or civilian is shot, killed or dies during an interaction involving a Contra Costa County police agency, the District Attorney’s Office launches an independent investigation. When no criminal charges are filed, the District Attorney’s Office will publish a public report detailing the facts and explaining the legal reasoning for this decision.
District Attorney Diana Becton said, “Transparency and accountability are fundamental to maintaining public trust. When a fatal incident occurs, my office is committed to conducting a comprehensive, independent investigation and sharing our findings with the community in a detailed public report.”

As previously reported, at approximately 6:16 am on June 30th, 2025, Antioch Police Department Dispatch received multiple 911 calls from David Bahrami, who lived with his family in Antioch and had a history of mental illness. He told dispatch he was about to kill someone, gave his address, and hung up the phone.
Multiple Antioch Police Officers staged nearby and called Bahrami to open a line of communication and to de-escalate the situation. At approximately 7:40 am, he threatened to kill his neighbor if officers did not come to his house. As a result, officers asked him to come outside to draw him away from family members inside the home.
Emerging from his residence, Bahrami walked toward the officers’ location approximately four houses away. Officers ordered him to stop and get on his knees, but instead he pulled out a large kitchen knife from his waistband and began running toward them. One officer fired a single less lethal round, which had no effect.
Bahrami continued running in a semi-circular path, then changed course and ran toward the police with the knife in his hand. When he was approximately 15–20 feet away, officers discharged their firearms to prevent themselves from potentially suffering great bodily injury or death from an imminent knife attack. He sustained multiple gunshot injuries and fell to the ground with the knife still in his hand. Officers immediately began administering medical aid, but Bahrami died at the scene.
During this encounter, responding officers repeatedly attempted de-escalation tactics by staging nearby and establishing communication with Bahrami. When confronted with an armed individual, Antioch officers elected to use less-lethal force. Officers resorted to lethal force only when Bahrami continued to wield his knife in direct proximity to the officers. Under the applicable legal standards, the District Attorney’s Office has determined that the officers acted in lawful self-defense/defense of others.
About the Report
The report is the final step in the CCCDAO investigation of the Antioch Police Department’s officer involved fatal incident of David Wali BAHRAMI on June 30th, 2025. The CCCDAO and every law enforcement agency in Contra Costa County follows the Law Enforcement Involved Fatal Incident Protocol (“the Protocol”)2 when investigating incidents where officers or civilians are shot, killed, or die during an encounter with law enforcement. Under the Protocol, the CCCDAO investigates all in-custody deaths in Contra Costa County for the purpose of making an independent determination of criminal liability. The sole purpose of the District Attorney investigation is to determine if there is proof beyond a reasonable doubt that an individual involved in the law enforcement involved fatality committed a crime.
Pursuant to the Protocol, immediately after an in-custody death, the involved law enforcement agency is required to notify the appropriate district attorney personnel. Once notified, trained and experienced members of the District Attorney’s Office respond to the scene and begin the criminal investigation. In addition, criminal investigators from the law enforcement agency involved in the incident and from the jurisdiction where the incident occurred, if different, respond to the scene as well. It is important to note that although these investigations happen simultaneously, each agency conducts its own independent investigation.
As part of the criminal investigation, law enforcement officers and civilians who witnessed the incident may be interviewed. Evidence is collected at the scene and may be submitted to the county crime lab for testing and analysis, in addition to any other relevant investigative work necessary to complete the investigation. The Contra Costa County Sheriff’s Office Crime Lab responds to every incident and is responsible for evidence collection of all in-custody deaths.
During the course of the criminal investigation, an officer or deputy has the right to be represented by an attorney. They may voluntarily choose to provide a statement, physical evidence, or other relevant information during the criminal and administrative investigations. Under the law, neither an officer nor civilian can be compelled to give a statement as part of a criminal investigation. However, an officer may be compelled to provide a statement during the law enforcement agency’s administrative investigation only.
The report includes a timeline of the actions of Bahrami and each officer. Witnesses included Bahrami’s sister, brother, father and mother.
A copy of the report has been sent to the Antioch Police Department, the California Department of Justice and is available to the public on the Contra Costa District Attorney’s website. (WARNING: The report contains graphic images)

Former Antioch Police Officers Timothy Manly Williams (left) and Daniel Harris (right) were sentenced on Jan. 13, 2026, to time served. Herald file photos
No prison time; both testified against former colleagues
By Allen D. Payton
The final cases of Antioch Police Officers that were the focus of the Contra Costa DA and FBI investigations were settled last month with two former officers given sentences of time served. As a result, Timothy Manly Williams and Daniel Harris will not face any time in prison. Both testified against their former colleagues.
According to a previously published report by the U.S. Attorney’s Office Northern District of California, Manly Williams pleaded guilty on Nov. 28, 2023, to destruction, alteration and falsification of records in federal investigations, obstruction of official proceedings and deprivation of rights under color of law. Manly Williams was sentenced to “six months’ custody, followed by three years of supervised release, and 100 hours of community service.
Harris pleaded guilty on Sept. 17, 2024 to conspiracy to distribute and possess with intent to distribute anabolic steroids, and possession with intent to distribute anabolic steroids as well as bank fraud. Harris was sentenced to “twelve months and a day of custody, followed by three years of supervised release, and 100 hours of community service.”
Both men’s sentencing hearings were held on Jan. 13, 2026, but no statement was issued by the U.S. Attorney’s Office Northern District of California, which prosecuted both cases.
Manly Williams’ Case Details
According to the Sentencing Memorandum for Manly Williams, “In May 2021, the Antioch Police Department (“APD”) discovered during a routine audit something surprising: their own police officer, Timothy Manly Williams, had called a subject of a wiretap he was monitoring. From all appearances, he had intentionally burned the wire and attempted to cover it up. A sprawling federal investigation would eventually result in various criminal charges against ten Antioch or Pittsburg Police Department (“PPD”) officers or employees, including Manly Williams.
“In August 2023, Manly Williams was indicted for his concealment of that call during the wiretap, which constituted criminal falsification of records and obstruction of justice, as well as for his unconstitutional destruction of a citizen’s cell phone following his then-roommate APD Officer Morteza Amiri’s release of a police canine to bite a suspect.
“By September 2023, Manly Williams had already met with the government a first time. By November 2023, he had promptly pleaded guilty to his crimes. In March 2025, he testified in the jury trial involving that same former roommate regarding another dog bite for which he was present, and Amiri’s concealment of facts surrounding that bite. He also admitted to additional criminal conduct not specifically referenced in the indictments.
“Manly Williams’ crimes were very serious, particularly given his role as a police officer sworn to uphold the law and protect his fellow citizens. However, his immediate acceptance of responsibility and cooperation with the government was also very significant, particularly given that same role, and the government accordingly moves for a downward variance pursuant to § 5K1.1 for his substantial assistance to authorities.
“Based on the nature and circumstances of the serious offenses, the defendant’s history and characteristics (including his role as a sworn police officer), the need for deterrence, and the need to avoid unwarranted sentence disparities given the sentences already imposed by this Court, as well as the government’s motion for the equivalent of a five-level downward departure pursuant to § 5K1.1, the government recommends that the Court impose a sentence of six months’ custody, followed by three years of supervised release, and 100 hours of community service. This proposed sentence is sufficient, but not greater than necessary, to achieve the goals set forth in 18 U.S.C. § 3553(a)(2).
“The government’s investigation also revealed other relevant criminal conduct, which Manly Williams admitted carrying out, including:
• While employed as a police officer with PPD and APD, Manly Williams illegally purchased anabolic steroids, Schedule III controlled substances, from PPD Officer Patrick Berhan and APD Officer Daniel Harris.
• While employed as a police officer with PPD and APD, Manly Williams misused confidential law enforcement databases by performing searches for the benefit of himself or friends without a proper law enforcement purpose. For instance, in approximately December 2020 he searched for the criminal history of his friend for no legitimate law enforcement purpose; and in approximately February 2021 he searched or caused law enforcement databases to be searched for warrants for no legitimate law enforcement purpose.
• While employed as APD police officers, Manly Williams and APD Officer Morteza Amiri illegally took marijuana and/or marijuana products seized from APD law enforcement activity, including in approximately December 2020 when Amiri stated to Manly Williams, “I got a basketball size bag of weed in my trunk.” Instead of filing reports with APD on the seizures of marijuana or submitting the marijuana into evidence, Amiri and Manly Williams personally consumed the marijuana in violation of APD policy and, in at least one instance in approximately November 2020, Manly Williams arranged for the sale of such marijuana and received proceeds from its sale.
• While employed as an APD police officer, Manly Williams illegally facilitated the removal or dismissal of traffic tickets for the benefit of himself, friends, or colleagues without a proper law enforcement purpose, including in approximately October 2020 via other APD officers in which the recipient of a ticket provided tequila bottles in exchange for those officers not appearing in court for a traffic ticket, and in approximately April 2021 at the behest of a PPD, who requested that a particular traffic ticket be disregarded.
• While employed as an APD police officer, Manly Williams wrongfully posted law enforcement-sensitive information to his Instagram account using the story feature to “close friends” who were outside the law enforcement community.”
The Memorandum also explained, Manly Williams had no previous arrests and did not have criminal convictions resulting in any Criminal History Points, placing him in Criminal History Category I and “the government agreed with the Sentencing Guidelines calculation of the United States Probation Office.
According to his Sentencing Memorandum, “Defendant Daniel Harris, a police officer with the Antioch Police Department (“APD”), began purchasing illegal anabolic steroids for his own personal use around 2019. He then began selling and distributing these Schedule III controlled substances to numerous other law enforcement officers at APD and neighboring law enforcement agencies. Among others, Harris sold illegal anabolic steroids to fellow APD officer Devon Wenger, and also agreed with Wenger to distribute them to Wenger’s friend B.M. Harris’ prolific sale and distribution of illegal anabolic steroids continued through March 2022 as he was in the process of moving from California to Texas, only coming to a halt after the FBI executed search warrants that located and seized troves of illegal anabolic steroids from a postal package destined for Harris (including steroids for Wenger’s friend), from Harris’ California residence, and from Harris’ new residence in Weatherford, Texas.
“The government’s investigation also revealed that Harris’ criminal activity while employed as an APD officer was not limited to the purchase and distribution of illegal anabolic steroids: he further committed bank fraud by falsifying information in his application for a mortgage to purchase his Texas residence.
“Harris’ crimes were particularly serious given Harris’ role as a law enforcement officer sworn to uphold the law. However, following his indictment and arrest, Harris took responsibility for his actions and pleaded guilty to all of these crimes, agreed to meet with the government and cooperate, and ultimately testified before the jury as to his and Wenger’s conduct involving the distribution of illegal anabolic steroids.
“Based on the nature and circumstances of the serious offenses, the defendant’s history and characteristics (including his role as a sworn police officer), the need for deterrence, and the need to avoid unwarranted sentence disparities given the sentences already imposed by this Court, as well as the government’s motion for the equivalent of a three-level downward departure pursuant to § 5K1.1, the government recommends that the Court impose a sentence of twelve months and a day of custody, followed by three years of supervised release, and 100 hours of community service. This proposed sentence is sufficient, but not greater than necessary, to achieve the goals set forth in 18 U.S.C. § 3553(a)(2).”
In addition the Memorandum explains, “In February 2022, Harris knowingly supplied inaccurate information to a financial institution in connection with his application for a mortgage. During this time, Harris applied for, and subsequently received, a $494,000 loan from Mortgage Financial Services LLC with the intent to defraud the financial institution to purchase a residence…in Weatherford, Texas. Harris provided false information in and omitted material facts from his application.”
ANTIOCH, CA — The City of Antioch has been awarded a $2,000,000 grant through the California Violence Intervention and Prevention (CalVIP) Grant Program, administered by the Board of State and Community Corrections (BSCC), following approval at the Board’s February 12, 2026 meeting. The funding will support expanded public safety strategies and community-based initiatives focused on prevention, intervention and long-term community stability, including coordinated partnerships and evidence-based services aimed at reducing violence and improving neighborhood safety.
The grant allows the City to initiate program activities beginning April 1, 2026. City staff will work closely with the BSCC to complete the contract process and fulfill all required onboarding and compliance steps associated with the award. Implementation will include structured reporting and performance monitoring to ensure accountability and measurable outcomes.
“This $2 million investment reflects confidence in Antioch’s approach to building safer neighborhoods through collaboration, accountability and data-informed strategies,” said City Manager Bessie Marie Scott. “These funds will allow us to expand programs that address root causes and improve outcomes for our community.”
“This award enhances our ability to deploy focused prevention and intervention strategies that reduce recidivism and improve public safety,” said Chief of Police Joe Vigil. “We will align these resources with evidence-based practices and community partnerships to ensure measurable impact.”
“This grant provides critical support for sustainable, community-centered initiatives,” said Monserrat Cabral, Director of Public Safety and Community Resources. “Our priority will be transparent implementation, performance tracking, and responsible management of these resources to ensure long-term benefits for Antioch residents.”
Additional information regarding program rollout and implementation milestones will be released as the agreement is finalized.
