Convict in Maine federal prison for gun arrest charged with wild caught-on-camera slay at East Harlem liquor store

A convict doing time in a Maine federal prison for a gun arrest has now been charged with murder for a caught-on-camera shooting at an East Harlem liquor store last year, police said Wednesday.

Camby Wilson was extradited to New York City Tuesday and charged with murder and gun possession for allegedly killing Shaquell Gainey, 25, the night of Feb. 25, 2022.

Wilson, 24, had been convicted of federal firearm charges in Bangor, Maine, and was sentenced to 24 months in prison in May, federal officials said.

Gainey had just stepped out of I.C. Liquors Inc. on First Ave. near E. 115th St. when a man dressed in all black spotted him, pulled out a gun and opened fire, cops said at the time.

Gainey retreated back into the store, followed by the gunman, who quickly ran back out.

Ninety seconds later, Gainey walked out of the store, his blood-stained yellow hoodie revealing where he was shot, the video shows. He dropped his jacket on the floor, walked into the deli next door and collapsed near the glass door.

For the next 90 seconds, Gainey sipped from a jug of water he found. While one customer retrieved Gainey’s jacket, no one tried to administer aid.

One man, carrying a small child, is seen on video stepping over Gainey. Medics rushed Gainey to Harlem Hospital but he could not be saved.

Gainey was just a block from his home in the Jefferson Houses when he was shot.

The gunman was with three other men when he spotted Gainey. The shooter kept walking, then doubled back and shot Gainey.

Police said there is a gang element to the shooting but did not have further details Wednesday.

Wilson was paroled in April 2021 after serving more than a year in state prison for a Manhattan weapon conviction, records show.

A few weeks after allegedly shooting Gainey, Wilson was a passenger in a car that cops in Augusta, Maine, pulled over.

Wilson gave the officers a false name as cops asked him to step out of the car. When the officers asked if he had any weapons on him, he ran off but was captured after a brief foot chase.

Officers found a loaded .380 caliber pistol in his jacket pocket, federal officials said. His weapon possession conviction in New York barred him from carrying a firearm.

NYPD detectives found Wilson in a Maine federal prison, where he was serving a two year sentence for the firearms arrest in Bangor, federal officials said.

Gainey had several arrests on his record, police said, including for robbery and weapon possession.
