Pasco police are looking for a 21-year-old Pasco man who hasn't been seen by family or friends since July 10.
Peter Sullivan was reported as a "missing endangered person," and friends fear he may have become disoriented and is in need of medical assistance, Capt. Jim Raymond said.
Sullivan did not show up for work July 10 at the Pasco Walmart and hasn't returned home since.
Friends and police have searched for him in vain since the following day.
Never miss a local story.
"There have been vague reports that he has been seen around the Tri-Cities area since disappearing," Raymond said. "Peter is not the type of person to have just disappeared and has not displayed those behaviors in the past."
Sullivan is about 225 pounds with blond hair and blue eyes.
Anyone with information about his whereabouts is asked to call police immediately.
