Detectives started monitoring the inmate’s phone calls months ago.

Jailed on assault and robbery charges, Michael L. Olson (left) had fled police after a fiery car crash that killed his girlfriend June 19.

He was arrested that night, accused of stealing a car and assaulting the owner, Christopher T. Fuller, 24.

Now Olson, 31, is suspected to trying to hire his cellmate at the Spokane County Jail to kill Fuller.

Investigators searched Olson’s mother’s home at 3715 N. Audubon St. on Thursday, seizing letters apparently written by Olson that discuss a murder plot, according to a search warrant filed in Spokane County District Court.

The evidence could help support charges of tampering with a witness and criminal solicitation to commit first-degree murder, according to the warrant.
