About 200 people searched for a Maryland man with dementia who disappeared Tuesday morning.
Daniel DeHaven -- a 65-year-old man who is nonverbal -- was last seen at 11:30 a.m. Tuesday at a Costco store on the 10900 block of Baltimore Avenue in Beltsville.
A group of volunteers who organized online searched neighborhoods in the area on Saturday and are expected to head back out on Sunday. They asked anyone with outdoor surveillance cameras to check the footage to see if anyone with DeHaven's description appears.
People should gather at 11 a.m. on Sunday, Jan. 7, at the Beltsville Volunteer Fire Department Fire House 31 on 4911 Prince George's Avenue in Beltsville, Maryland.
DeHaven's family hopes he found someplace warm to rest and has been there.
"We're just trying to stay focused on keeping hope going, and focusing on the search," DeHaven's son, Kevin, said.
"We're not going to stop, because he wouldn't stop," Kevin DeHaven said. "If it were any of us, he wouldn't stop."
Police and volunteers have been searching for Daniel DeHaven around the clock despite snow and blustery temperatures.
"The snow that's coming and the dipping temperatures are not on our side," Prince George's County Police Department spokeswoman Jennifer Donelan said Wednesday.
Police in Greenbelt, Laurel and Montgomery County, as well as federal officials, are helping search for Daniel DeHaven.
Daniel DeHaven, who goes by Danny, did not have identification with him when he disappeared.
"He's a kind man. He's approachable. If you see him, he's not able to communicate, necessarily, but if you call out 'Danny,' he'll know his name and most likely, you'll be greeted by a smile," his son said.
Police received a tip that a man meeting Daniel DeHaven's description was seen in downtown Silver Spring, but they were unable to find him.
Daniel DeHaven is 5 feet 9 inches tall and weighs 175 pounds. He has brown eyes and partially gray hair, police said.
He was last seen wearing a gray hat, black coat and blue jeans.
Anyone with information on Daniel DeHaven's whereabouts is asked to call police immediately at 301-699-2601.
