Officer Hector Jimenez wrote in a probable cause statements that officers who went to a residence in the 9400 block of Dunbar Drive at 12:21 a.m. on Friday to investigate a report of gunshots found a male, identified in court documents as Toto M. Diambu, lying in front of the residence suffering from an apparent stab wound.

Jimenez said that as the officers were providing aid to Diambu they heard a loud bang coming from the garage and then saw Rivers walking out of the residence covered in blood.

Rivers was detained and when they searched her they found ammunition in her pocket along with knives, according to Jimenez.

As officers were detaining Rivers she began making spontaneous statements about her involvement in the murders, Jimenez said.

When officers continued search the residence they found the other two victims, identified in court documents as Charlotte Kuulei Reed and Patricia A. Wright, inside of the residence suffering from both apparent gunshot wounds and stab wounds, according to Jimenez.

The arson count alleges that Rivers willfully, unlawfully and maliciously set fire the residence.
