PORTLAND, Ore. (KOIN) – A man who barricaded himself in a burning garage in Southeast Portland and held police at bay for hours was taken into custody Wednesday afternoon.

The suspect, 43-year-old Shawn Mahan, was hiding in a shed behind a home near 127th and Powell after allegedly stabbing a 60-year-old man.

The homeowners knew Mahan and called police when he began acting erratic and uncooperative. When officers arrived and spoke to the residents, they saw smoke coming from the detached garage.

Mahan barricaded himself in the garage for several hours as Portland Police Bureau’s Special Emergency Reaction Team and Crisis Negotiation Team and fire officials tried to get him to come out so they could fight the fire.

The combination of the fire and tactical situation made this a unique case for authorities. Officers weren’t able to enter the burning building due to safety concerns, so a robot was used to get a closer look at the suspect’s activity.

“We don’t often have a tactical incident and a fire at the same time,” Sgt. Pete Simpson said.

Mahan eventually did leave the burning structure and was taken to the hospital for treatment of smoke inhalation. He was not seriously injured and was later booked into the Multnomah County Jail for assault and a parole violation.

Portland Police said more charges may be added later as the investigation continues.

The stabbing victim did not have life-threatening injuries.

Mahan has had previous run-ins with the law, including a 2013 arrest for attempted murder, first-degree assault and felon in possession of a firearm after he allegedly shot his roommate in the leg.
