Killer thief’s hazmat suit is found in Bronx

The hazmat suit worn by the gunman who recently killed a Manhattan deli worker and pulled robberies at three other shops has been found, a top NYPD official said Wednesday.

The killer is still being sought. The Tyvek suit was located Tuesday night behind a building on Park Ave. near E. 158th St. in Concourse Village in the Bronx, according to Chief of Detectives James Essig.

Police tracked the suspect on video after he killed Sueng Choi, 67, during a botched robbery on the Upper East Side on Friday and fled on his scooter, sources said.

“He is seen going in there, into the rear of it ... on that scooter,” Essig said, “and when we went to the back we found that Tyvek suit.”

The building is a five minute walk from the Ya Ya Deli, located at Melrose Ave. and E. 160th St. The crook robbed it 22 minutes after killing Choi, arriving and leaving on the same scooter, according to cops.

The suit is being processed for DNA and fingerprints, Essig said.

Choi was likely shot as the suspect was pistol-whipping him inside the Daona Deli and Grocery, the Upper East Side grocery where the victim worked for 10 years and was well-liked by regular customers.

The killer, who got only a tray of lighters after the murder, had struck twice earlier in Brooklyn.

On March 1, he robbed the Super Deli Market on Manhattan Ave. in Greenpoint.

The gunman “calmly” demanded all the money in the register and five cartons of cigarettes, a worker recalled.

A similar robbery took place the night of Feb. 25 at the Sunset Bagel Shop in Ditmas Park. The crook placed a food order, announced a robbery, then fled with cash and several cell phones, police said.

Choi’s murder prompted another plea from the NYPD, and from Mayor Adams, for store owners to ask customers to unmask themselves upon entering a shop — at least long enough for their faces to be seen.

“Once you show the store owner who you are and everything’s OK, if you don’t feel comfortable in the store without your mask on, by all means put it back on,” Chief of Department Jeffrey Maddrey said Monday. “But we should be helping one another to feel safe.”
