WATCH Traffic Stop Leads to Stolen Weapons Discovery

Authorities are trying to figure out today what a Nevada man was doing near the University of Washington campus with a cache of weapons in a stolen truck.

On Wednesday at 10:30 p.m., University of Washington Police saw the blue pickup truck, which had been reported stolen in Montana, and conducted a traffic stop check, according to a news release from the Seattle Police Department.

A search of the vehicle yielded a stolen scoped rifle, stolen shotgun, suspected molotov cocktails and body armor, according to police.

"Any time you have someone who has body armor, long guns and incendiary devices, that's a significant concern," interim Seattle Police Chief Jim Pugel said during a Thursday news conference.

The suspect, who was identified as Justin Miles Jasper, 21, by ABC News' Seattle affiliate KOMO, was taken into custody without incident and booked into the King County Jail, according to police.

Jasper is being held on a charge stemming from the incendiary devices found in the vehicle, according to jail records, and is being held without bail.

Seattle Police said the FBI had joined the investigation, but it is not believed there is an active threat to the University of Washington community.
