OAKLAND — Two women have been charged for their suspected roles in the killing of another woman who died Oct. 2, three weeks after she was shot while riding in a car with them in East Oakland, according to authorities and court records.

Charged with murder and carrying a loaded firearm on one’s person in a city was Diamond Cooper, 19. Charged with being an accessory after the fact was Tonea Thomas, 19.

Authorities said the two suspects lived together in San Jose and were friends with the victim, Schevette Butts, 62, of Oakland.

Butts was shot Sept. 12 while a passenger in a car with the suspects. She died Oct. 2 at Highland Hospital.

According to authorities and court documents, the three were in a Honda Accord driving in the 7100 block of International Boulevard when the shooting happened. Thomas was driving, Butts was in the front passenger seat and Cooper was in the rear seat.

According to court records and authorities, Thomas passed a loaded semi-automatic pistol to Cooper who “manipulated” it in such a way a bullet was negligently fired, hitting Butts in the lower rear part of her body.

The two suspects drove Butts to Highland Hospital where they gave officers false information before leaving on foot, according to court records. The gun, a shell casing, and slug were recovered inside the car, authorities said.

The case originally was assigned to felony assault unit Officer James Pulsipher who was able to identify the suspects through video surveillance and witnesses. Both suspects were arrested in San Jose on Oct. 12 and were formally charged Friday.
