Previously, Riverside police said their preliminary investigation found that Bierma was a prostitute and Combs was one of her clients. Investigators added the arrangement between the two was unknown.
Combs was found dead by a family member who was concerned when they couldn’t reach him. His body was found inside the kitchen after being stabbed with a pair of scissors, the prosecutor’s office spokesperson said.
The relative reported Combs’ cell phone was missing which led investigators to “ping” it, revealing its location in another part of Riverside. The track led police to Bierma, who was in possession of the phone, the spokesperson said.
