A 22-year-old man fatally shot by Vancouver police was an Oregon Army National Guard soldier who served 12 months in Iraq, a National Guard spokesman confirms.

Spc. Nikkolas W. Lookabill deployed in May 2009 as a member of the 41st Infantry Brigade after joining the guard in 2008, Guard spokesman Capt. Stephen Bomar said. Lookabill returned in May.

Police said three officers fired at the Vancouver man early Tuesday morning after they responded to a report of a man walking in a neighborhood, armed with a handgun. Police spokeswoman Kim Kapp said the man was "engaging in threatening activity" and refusing police commands to drop the gun when he was shot.

The Oregonian newspaper says Lookabill was part of a unit that provided gate and tower security at Camp Victory in Baghdad.
