Memorial service for slain Washington sheriff's deputy Justin DeRosier

KELSO, Wash. -- A memorial service for slain Cowlitz County sheriff's deputy Justin DeRosier was held Wednesday in Portland, Oregon.

The body of Cowlitz County Deputy Justin DeRosier was escorted earlier Wednesday from Longview, Washington to Portland,.

Several thousand mourners, including hundreds of law enforcement officers, are attending his funeral at a stadium at the University of Portland.

DeRosier was killed while responding to a call about a disabled motorhome blocking a road in southwest Washington.

The 29-year-old was married with a 5-month-old daughter.

Authorities found suspect Brian Butts the next day and fatally shot him after they said he ran out of the woods armed with a handgun.

The Clark County Sheriff's Office says Butts had methamphetamine worth up to $3,000 on him when he was killed.

Oregon Gov. Kate Brown has ordered flags to be flown at half-mast Wednesday in his honor.
