According to the Idaho State Police, the suspect, 34-year-old Marcus Lee Thompson, was named following a multi-agency investigation involving local, state, and federal law enforcement. Thompson, a resident of Ada County, is now wanted on two counts of first-degree murder and multiple weapons charges.

Incident Details

The attack took place as the firefighters, both members of the Boise Fire Department, responded to a reported vehicle fire along Highway 21.
