Police need the public's help to find a missing man in Brooklyn who hasn’t been seen since Tuesday.

Larry McKnight, 69, was last seen on Jan. 30 at 2 p.m. walking near the intersection of Utica Avenue and Pacific Street.

McKnight’s family is concerned because he has dementia, has no cellphone and they are worried he’s stuck out in the cold. They say he often goes to a nearby corner store and either to his or his girlfriend’s house, but has never gone this long without reaching out.

“I just want him home,” said his daughter Kysha McKnight. “The officers put out a Silver Alert and they are doing what they have to do but no one has found him. It is really scary.”

If you have any information on Larry McKnight’s whereabouts contact the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477).
