Explosives found in box detonated by bomb squad, Arrowhead Drive in Carson City reopens

UPDATE 2:15 PM: Mining explosives found in a box at an Arrowhead Drive residence in Carson City on Thursday morning led to an investigation and call to Douglas County Bomb Squad to detonate the box, apparently bought at an estate sale.

The incident forced the closure of portions of Arrowhead and I-580 and Arrowhead. According to Carson City Sheriff's Office Sgt. Dan Gomes, the bomb squad confirmed one box contained dynamite, blasting caps and det cord and did a controlled explosion of the box on scene.

The box came from an estate sale in Silver Springs. It was unknown to the residents, who lived in the 100 block of Arrowhead Drive, what contents were inside, said Gomes. However, when they returned home, then went through the box and saw dynamite and an item labeled crystalized dynamite.

That's when they contacted Carson City dispatch, which called out the sheriff's office and fire department to investigate shortly after 8:30 a.m. No one was injured.

For public safety reasons, Arrowhead Drive was closed 1,000 feet in each direction and nearby homes were evacuated. I-580 offramp at Arrowhead was closed, and reopened shortly before 2 p.m.

Carson City Sheriff's Office was assisted with road closures by Nevada State Police Highway Patrol and the Nevada Department of Transportation.
