By Acting Sergeant Santiago Castillo, Antioch Police Investigations Bureau

Sean Brown

On Monday, October 22, 2012, Antioch Police Detectives who were following leads they developed, located and arrested two adult Antioch residents for the murder of a 26 year old male that occurred on the previous Saturday. The arrest took place without incident and evidence linking them both to the crime was located and collected.

On Wednesday, October 24, the Contra Costa District Attorney’s Office filed murder charges on 45 year-old Sean Brown and 41 year-old Sonya Joseph for the stabbing death of 26 year-old King Gregory Carroll on Saturday, October 20. Along with the murder charge on Brown, he has also been charged with two enhancements, (3 strikes and personal use of a knife.)

Antioch Police Investigators believe the killing of Carroll was in retaliation for a fight earlier this month between Carroll and Brown in which Carroll won. Since then, Brown and Joseph dwelled over the loss of the fight and actively pursued retaliation. During the late night hours of 10/19/12, Joseph and Brown located Carroll at the Manzanita Dr address and a fight ensued in which Brown stabbed Carroll numerous times with a large knife.

Anyone with information is asked to call Detective James Stenger at (925) 779-6894 or (925) 779-6927.
