University of Washington police first spotted a man sleeping in a pickup truck near the campus on Tuesday night. Officers ran the vehicle through a police database and didn't get any hits, so they let the man go, according to University of Washington Police Chief John Vinson.
The following day, police received word that the same truck had been reported stolen out of Butte, Montana. Officers returned to the area where they saw the man on Tuesday, but he was gone.
At about 10:30 p.m. on Wednesday, UW officers once again spotted the truck in the 3400 block of Sand Point Way NE. They stopped the truck and arrested the driver, 21-year-old Justin Miles Jasper of Nevada.
While searching the truck, police found a stolen scoped rifle, a stolen shotgun, body armor and several incendiary devices.
"They were well made devices. Some would call them molotov cocktails," interim Seattle Police Chief Jim Pugel said during a Thursday press conference.
Police say there does not appear to be any threat to the University of Washington community, but the FBI and Seattle Police Department have joined the investigation.
While he says there is likely no active threat, Pugel admits the case is concerning.
"Any time you have someone who has body armor, long guns and incendiary devices, that's a significant concern," he said.
Jasper is set to make his first court appearance on Friday afternoon.
