BEND, Ore. -

Oregon State police say a driver shot and killed himself in his vehicle following a standoff with police on Highway 20 near Bend.

State police say the Deschutes County sheriff's office received a call Saturday night that a man described as armed and suicidal was driving on Highway 20 in the Santiam Pass area.

State police spotted the driver, who sped away before being stopped just after 9 p.m.

Police say the man failed to follow any orders. Several agencies responded, including a Bend Police Department negotiator and state police SWAT personnel. Authorities closed the highway in both directions during the standoff.

About an hour after the man was stopped, officers were able to check on his vehicle. They found him dead from an apparent self-inflicted gunshot wound.
