Several blocks around a residence in Silverdale, near Ridgetop Middle School, were cordoned off Friday as law enforcement investigated possible explosive devices at the house.

The location, on the 10900 block of Peony Place NW, is in a residential neighborhood across Ridgetop Boulevard and is not on the direct route to or from the school.

Kitsap County sheriff’s Lt. Earl Smith said authorities restricted access to the area out of an abundance of caution. He urged residents to check for updates on the sheriff’s office’s Facebook page.

“It takes time, and when dealing with explosives or possible explosives we have to go real slow and methodical to make sure everything goes safe,” Smith said.

The incident started when deputies were called at 10:09 a.m. after receiving reports that a man was in mental crisis and had fired a gun inside the residence. He was taken into protective custody and was then taken to a local hospital for treatment. He was not arrested, though Smith said he could face criminal charges.

Family members of the man told authorities there may be incendiary or explosive devices in the residence. After a preliminary investigation local, state and federal bomb experts were called to the scene. In addition to local and Washington State Patrol officers, Smith said officers from the FBI, Naval Criminal Investigative Service and the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives were on scene.

“We are pretty confident there are some kind of incendiary devices at the residence,” Smith said, adding that deputies were writing an application for a search warrant to go inside the house.
