Missing Shin Noh fed by homeless, searchers told

There are unconfirmed reports that homeless people in the Burke Mountain area may have been feeding a Coquitlam man with Alzheimer's disease who went missing last week.

Police say Shin Ik Noh, 64, was last seen by his wife at 10:30 a.m. PT on Sept. 18 when he left his home near the Lansdowne Drive and Guildford Way area for his morning walk. When he didn't return a few hours later the family called police.

His son Sam Noh says he has been told by several searchers that homeless people think claim they have been feeding the elderly man — but the the sightings have yet to be confirmed.

The family has been organizing daily searches of the area after the elderly Korean-Canadian man was spotted in three different places around the Burke Mountain area.
