EVERETT, Wash. -- The roommate of a woman who was found stabbed to death in south Everett in late May has been charged in her death.

Tammie Jo Peterson, 54, was charged Friday with first-degree murder in the death of Deborah Jeanneret, 50. She had been accused of covering up the crime and had been charged with rendering criminal assistance.

Court documents say Jeanneret was stabbed about 40 times and that a tip of a knife was embedded in her skull.

At first, police arrested Peterson's former boyfriend in the slaying but the case against him was dismissed. He wasn't in Everett at the time of the slaying, court documents say.

Peterson had told detectives that her former boyfriend had killed Jeanneret. After the case against him was dismissed, Peterson told detectives that the victim's former boyfriend had killed her, court documents say.

That man passed a lie-detector test, and detectives determined the accusations against him were not credible, court documents say.

Detectives discovered that Peterson took the victim's car, cell phone and credit cards. Court documents say she used the credit cards.

An acquaintance of Peterson's told police that Peterson had asked him to help her get rid of the murder weapon, court documents say.

He told police that Peterson wrapped the knife in a grocery bag and threw it in the Snohomish River.

A police diver found the knife. It was missing its tip and appeared to have blood staining on it, court documents say.

A long dark hair was wrapped around it. Both Jeanneret and Peterson have long dark hair, court documents say, and an autopsy found a long dark hair entwined in Jeanneret's fingers.

Bail for Peterson has been set at $1 million.

Prosecutors say she has an extensive criminal history and that nine warrants have been issued for her arrest in the last two years.
