A woman facing eviction from her Pinole home stands accused of shooting her mother in the head with an assault weapon before surrendering to police.
A call about a disturbance summoned officers to a house in the 4000 block of Marcas Street at 7:51 a.m. Sunday.
There they found 43-year-old Kimberly Petretti sitting at the curb. She told them to check inside.
Officers searching the house found 62-year-old Claudia Petretti dead in an upstairs room.
"It looks like the mother and daughter lived together. We have no motive at this point," Chief Paul Clancy said. "They were going to be evicted."
Detectives found an eviction paper that indicated the pair were supposed to be off the property at 6 a.m. Sunday. The house showed no signs of a preparation for the move.
"It looks like the victim was watching television in an upstairs sitting room" when she was shot in the head, Clancy said.
Police found an AR-15 rifle inside the house that they believe the younger Petretti used to shoot her mother. Detectives have had difficulty tracing the weapon.
Officers arrested Kimberly Petretti on suspicion of murder and booked her into County Jail in Martinez.
