ANTIOCH -- An Antioch couple has been charged with the murder in connection with the death of King Gregory Carroll Jr., whose body was found on the street Oct. 20, authorities said.
Sean Brown, 45, and Sonya Joseph, 41, both of Antioch, were formally charged with murder Thursday by the Contra Costa District Attorney's Office, said Antioch police Sgt. Santiago Castillo. Brown also faces two enhancements on the charge, a three strikes enhancement and one for personal use of a knife.
Carroll was found stabbed to death in the 2200 block of Manzanita Way around 12:44 p.m, Castillo said. Carroll had stab wounds and had been dead for some time when his body was found.
Investigators believe the death was an act of retaliation from a fight earlier this month between Carroll and Brown that Carroll had won, Castillo said. Officials allege that Brown and Joseph actively pursued retaliation, tracking down Carroll in the late-night hours of Oct. 19 and stabbing him numerous times during that fight.
On the day they were arrested, officers said both Brown and Joseph were found to be in possession of evidence linking them to the crime, including the knife believed to be the murder weapon, Castillo said.
