OAKLAND (KRON)—The suspect in an Oakland triple homicide involving a fire has been identified as 61-year-old Dana Rivers of San Jose, according to Alameda County officials.

Rivers was questioned Friday and arrested by police.

The incident happened at around 12:21 a.m. in the 9400 block of Dunbar Drive, police said.

Oakland police officers responded to shots fired and found a male victim in the street with apparent stab wounds. As they were attending to the victim, they noticed smoke coming from a nearby house.

The Oakland Fire Department responded and found two victims, both women, inside the house.

The women were suffering from stab wounds and gunshot wounds, officers said.

The fire has since been reported under control, but authorities have not clarified its connection to the suspect or victims.

All three victims have died.

An FBI team is helping with the investigation.
