(Portland, OR) -- A memorial is being held today for a Vancouver police officer who was shot to death by a Clark County Sheriff's deputy late last month. Officer Donald Sahota had been stabbed by an armed robbery suspect at his home on January 29th when the deputy mistakenly shot him. Police Chief James McElvain says the department is struggling with Sahota's death. McElvain says the department holds no ill will toward the Sheriff's Office or the deputy who fired the shot. He says the responsibility for Sahota's death is on the suspect who caused the shooting to happen. Sahota's memorial will be held at 1 p.m. at the ilani Casino Resort.
