By Ted Asregadoo, PIO, Contra Costa District Attorney’s Office
Martinez, California – The Contra Costa District Attorney’s Office announced Wednesday, Nov. 26, 2025, that a suspect in possession of child sexual abuse material faces a four-count felony complaint.
32-year-old Ryan Allen Fenton of Antioch (born 6/13/1993) was arrested in Antioch Tuesday by Walnut Creek Police on a warrant related to a complaint the District Attorney filed with the court on February 3rd, 2025. The complaint was amended and refiled on November 25th after investigators with the Internet Crimes Against Children Task Force found additional evidence Fenton was in possession of child sexual abuse material.
Fenton was arraigned Wednesday in Superior Court in Martinez at 10:30 am on the following:
· Two felony counts for possessing over 600 images of child or youth pornography on or about October 23rd, 2024, and November 25th, 2025 [PC 311.11(c)(1)].
· Two felony counts for possessing child or youth pornography on or about October 23rd, 2024, and November 25th, 2025 [PC 311.11(a)].
District Attorney Diana Becton said, “The possession of Child Sexual Abuse Material (CSAM) is not a victimless crime; it is an act that perpetuates the sexual abuse of children and fuels a criminal enterprise. As District Attorney, my office treats the possession of CSAM with the utmost gravity, recognizing that every image and video represents an assault on a child.”
Fenton’s preliminary hearing is set for December 9th at 8:30 am at the A.F. Bray courthouse in Martinez in Department 6. He remains in custody at the Martinez Detention Facility on a $200,000 bond.
Case No. 01-25-00447 | The People of the State of California v. Ryan Allen Fenton
According to localcrimenews.com, Fenton was also arrested in 2020 in Inyo County for speeding, driving without a license and failure to provide evidence of financial responsibility.
This morning, Tuesday, November 25, 2025, Walnut Creek Police Detectives, in coordination with the Internet Crimes Against Children (ICAC) Task Force, served a search warrant at a residence in the 1600 block of Lipton Street in Antioch as part of an ongoing investigation.
One individual was arrested on suspicion of possession of child pornography.
During the search, detectives discovered suspected illegal fireworks. The WCPD Bomb Squad was requested to respond for safe collection and assessment. Upon arrival, bomb technicians identified materials requiring further evaluation, prompting a response from the Contra Costa County Fire Protection District’s Hazardous Materials (Hazmat) team.
Antioch Police posted a warning on social media with the message, “Avoid the area of Lipton Street at Trembath Lane due to an active hazmat response. Earlier this morning, a neighboring agency investigating in the area located items of concern. Out of an abundance of caution, the bomb squad was notified, and they are currently on scene. At this time, we do not believe there is any threat to the public.”
Both the WCPD Bomb Squad and CFD Hazmat have since cleared the scene. There is no ongoing threat to public safety. No further details are being released at this time due to the active nature of the investigation.
