The Contra Costa County District Attorney’s Office has charged Jason Ivan Mosqueda, 39, of Richmond, with one count of murder, one count of violating a restraining order, and three counts of probation violation in connection with the killing of his brother at a home in the Montalvin Manor neighborhood on Sunday, according to the Contra Costa County Sheriff’s Office.
Mosqueda is being held at the Martinez Detention Facility without bail.
Just after 7 p.m. Sunday, the sheriff’s office responded to a home in the 1700 block of Lettia Road after a resident reported that her injured son, identified as Edward Mosqueda, 42, of Concord, was unresponsive.
Deputies arrived and started CPR on the victim but he was later pronounced deceased, the sheriff’s office said.
An investigation led to the identification of Jason Mosqueda as the suspect.
“He was located by deputies several blocks away” and arrested without incident, the sheriff’s office said.
At the time of his arrest, Jason Mosqueda had arrest warrants for domestic violence, elder abuse, stalking and violation of a protective order, the sheriff’s office said.
Further details about what happened Sunday weren’t immediately available.
