The family of a missing Coquitlam man with Alzheimer’s disease has received multiple tips that he’s been getting by with help from homeless people in a local park.

Shin Ik Noh’s wife and children haven’t heard from him since the 64-year-old left home on his morning walk last Wednesday near Lansdowne Drive and Guildford Way.

Mounties confirm there were sightings of Noh over the weekend in the Burke Mountain area, and his son Sam Noh told CTV News the family has received more encouraging news from Gates Park.

“We actually received tips from two different homeless people that they were feeding an Asian male with a hat on and a plaid shirt,” he said.

Noh left home in a black New York Rangers cap, dark green pants, and a green-and-navy plaid shirt with long sleeves.

Another homeless man said he saw a man matching Noh’s description sleeping underneath a tarp.

On Wednesday, the family organized two group searches, one beginning at 11 a.m. and the other at 6:30 p.m. Teams of volunteers, many of whom have never met Noh, showed up to help scour local parks and trails to bring him home.

“We’re joining because my mom has Alzheimer’s and it really touches me when I see someone like this who’s gotten lost because it can easily happen to her,” said volunteer Yasmin Pickering.

Noh’s family said he’s in good physical shape and can walk long distances. He speaks fluent English, but has lost some of his vocabulary due to his condition and usually prefers to speak in his first language, Korean.

The family said Noh is a former Pastor and exceptionally friendly, and they’re asking anyone who sees him to not just call 911, but approach him as well.

“We’re getting a lot of possible sightings, and by the time [witnesses] call 911 that individual is gone,” Noh’s son said.

Mounties said Noh never forgets Sam’s name, or the names of his daughter Rebecca and granddaughter Natalee. Anyone who approaches him is advised to mention his family members.

Noh is described as 5-6 tall and 160 lbs. with an average build. He has short black hair that’s greying on the sides.
