Vancouver Police are looking for a 69-year-old man with dementia, missing since Thursday morning.
Gary Ostertag was last seen leaving his home in the 4600 block of Oak Street at 11:30am.
Cold wet weather have police concerned for his safety, and they're appealing to the public for help in finding Ostertag.
Police have searched public transit, his neighborhood, taxi companies and local hospitals without turning up any trace of him.
Ostertag is 5'4" tall with a slim build and white hair. He has a scruffy white beard, and wears prescription glasses with dark frames.
At the time he disappeared, he was wearing a dark fleece jacket, light coloured pants and may have a lanyard with an identification tag around his neck.
