A search warrant filed today in Spokane County District Court reveals new details about a bizarre carjacking that led to the death of one of the suspects in a fiery car crash last month.
Marjorie A. "Amy" Harrigan, 24, died when she was thrown from the carjacked 2002 Acura RSX during a police chase you can read about here.
Harrigan's boyfriend, Michael L. Olson, 31, was arrested later that day and accused of stealing the Acura with Harrigan and assaulting the car's owner.
Police say he was in a Chevy pickup truck driving near Harrigan in the Acura when police spotted them.
The search warrant filed today shows Olson had another girlfriend who he was cheating on with Harrigan, and that woman told police she'd given Olson a spare set of keys to the truck, according to the search warrant prepared by Spokane County Sheriff's Detective Lyle Johnston.
But that was a few weeks ago when he was working for the owner, she told police, and she knew Olson wasn't supposed to be driving it the night of Harrigan's death, Johnston said.
The warrant authorized a search of a backpack found at Olson's mother's house. Inside, detectives found cell phones belonging to Olson, Harrigan and the carjacking victim.
Johnston filed another search warrant shortly after asking T-Mobile and Cricket for information on the phones.

Olson was arraigned last week and remains in Spokane County Jail on charges of first-degree robbery, first-degree assault and three counts of driving with a suspended license.
His bail is set at $76,950.
