Man Arrested for Murdering his Brother at their Mother’s Home

SAN PABLO — A family gathering turned into a tragedy last weekend. A man was killed while visiting his mother, and his brother was arrested on suspicion of murdering him.

Contra Costa County Sheriff’s Office deputies were dispatched to Montalvin Manor, an unincorporated community outside of San Pablo. This call for medical and law enforcement help was received January 3 at 7:02 p.m.

A resident living at 1175 Lettia Road reported her son was injured and unresponsive. Responding deputies performed CPR on the man, but it was already too late. The victim was pronounced dead after paramedics arrived on the scene.

The victim was 42-year-old Edward Mosqueda of Concord. His brother Jason Mosqueda, 39 of Richmond, was identified as a suspect by deputies.

The residence was thoroughly searched before deputies located the suspect a few blocks away. He was questioned by homicide detectives and arrested without further incident.

The younger Mosqueda was booked into the Martinez Detention Facility. He remains in custody in lieu of $1 million bond.
Mosqueda faces charges for first degree murder and violation of a protective order. In addition, he was arrested for outstanding warrants for domestic violence, elder abuse, and stalking.

The suspect was on probation for a prior conviction, and he is charged with violation of probation for re-arrest.
