Owen Rooney, 24, walked away from the hospital with his belongings in Grand Forks on Aug. 14, 2010, and he has not been heard from since. He had sustained a head injury on Aug. 12.
He is five-foot-nine and weighed 160 pounds, has an Australian accent and has tattoos on his right calf and on his shoulder.
Rooney worked at Big White in Kelowna for the past two winters and at a restaurant in Kelowna until his disappearance.
Local RCMP Const. Chris Manseau says the local detachment received a tip March 21, following the airing of Rooney's story on the Fifth Estate on March 11. A caller said Rooney was spotted in the 100 Mile House area around about two weeks earlier.
Noting all known witnesses were spoken to and it is believed it was a case of mistaken identity, Manseau says the investigation is still ongoing.
Anyone who may have information on the disappearance or has seen Rooney is asked to call the 100 Mile House RCMP at 250-395-2456 or Crime Stoppers at 1-800-222-TIPS (8477).
