Tax records show Doucette is the property owner at 14802 N.E. 33rd St. The suspect's MySpace page says he is married, a father and served as a combat engineer in the Marine Corps.
A spokesman for First Response Inc. said Tuesday night that Doucette has been an employee with the security services company for four years and worked as an armed guard for one year.
The company said he owns his own weapon and was off-duty at the time of the incident.
The spokesman said Doucette is licensed by the Oregon Department of Public Safety Standards and Training as an armed security guard and has been a "great employee and we're sorry this happened for all involved."
Police records show Doucette does not have any prior arrests in either Oregon or Washington.
James Halk said he was sleeping on his friend's couch before a morning fishing trip when loud voices woke him up around 4 a.m.
"I didn't know exactly what was going on. I thought they were loading the boat. That was not what was going on. I just heard screaming. 'You'd better stop. You'd better stop.' And next thing I heard was the gunshot," Halk said.
Halk said he stayed inside until police arrived. When he walked out, he saw a man's body.
"It was in the street," Halk said.
Later in the day, Halk said officers came to his friend's home to investigate car break-ins on the street. Vancouver police have not said whether that investigation is linked to the shooting.
The identity of the man shot and killed has not been released and is pending positive identification by the Clark County Medical Examiner's Office.
Victoria Kovton worries it may be her friend. They were drinking at a friend's house in the neighborhood and Kovton hasn't heard from him since he left around the time of the shooting.
"I haven't slept the whole frickin' night, walking back and forth here because I don't know if that's my friend out there," she said.
The investigation is continuing and no additional details about what led up to the shooting are being released by police at this time.
Doucette is set to make his first court appearance Wednesday morning.
Vancouver police reopened the street Tuesday after having it taped off for nearly 12 hours while officers collected evidence.
