It's been one month since 26-year-old Colin Marma, of Garrison, went missing. On Sunday, a group of his loved ones headed into Manhattan to look for him.

Family and friends say Marma was last seen on Feb. 2.

They organized group searches in the city to find him ever since.

As of Sunday night, a group of volunteers canvassed local hospitals, food pantries, shelters and police precincts.

They handed out flyers with Marma's information on it and pleaded with everyone they meet to keep an eye out for him.

Marma's stepfather, Roland Heitmann, told News 12, about their search plan.

"Because of the beautiful weather, we know that he likes walking around outside, so we're gonna canvas the parks today and were also gonna try to hit as many subway stations cause we think that's a likely spot for him," Heitmann said on Sunday.

Marma's parents said their son's car was found in Manhattan, They ask anyone with more information regarding his whereabouts to call 212-694-7782.

He was last seen wearing black pants, a black sweatshirt, a black beret and red sneakers.
