Suspect arrested in case of bomb at MLK day parade

Posted: Updated:

SPOKANE, Wash. – Federal authorities have arrested a person allegedly connected to a backpack bomb found during a Martin Luther King parade in Spokane in January. Federal agents called the backpack bomb an act of "domestic terrorism" and their agency's highest priority in the Spokane area.

The suspect has been identified as 36-year-old Kevin Harpham of Addy, Washington. Witnesses in Stevens County say at least nine FBI vehicles sped towards a house near Highway 395 south of Colville. At least two counter-assault vehicles were also at the house.

City workers found a suspicious backpack along a parade route on Martin Luther King day where thousands of people were scheduled to march.

Authorities later determined the backpack contained a bomb at least one agent described as, "the most sophisticated" he had ever seen.
