ID in slaying of B’klyn teen

One of two suspects in the shocking murder of a Brooklyn teen has been identified, police said Monday.

Martial Amilcar is being sought for the Feb. 22 execution of Samuel Joseph, 15 (photo), in what might have been a case of mistaken identity. The killing was captured on surveillance video.

Sources said the suspects were caught on video at the time of the 5:45 p.m. attack waiting outside the boy’s apartment on Flatbush Ave. near E. 26th St. As Samuel stepped outside, one of the two opened fire. The teen’s sister was just a few feet away from Samuel, who was rushed to Kings County Hospital and died, police said.

Moments earlier the suspects had approached the sister. NYPD Chief of Investigations William Aubry said Amilcar “indicated that he was looking for the older brother.”

A police source with knowledge of the case told the Daily News at the time of the killing that the gunman may have confused the boy, the youngest of eight, with his older brother. Police sources said his brother may have gang ties.

Samuel, the son of Haitian immigrants, was blasted in the face, neck and chest by one of the two assailants.

Samuel spent his free time playing basketball at a YMCA near his home. Friends said Samuel had recently been denied access to the YMCA because he couldn’t afford a pass. If he had one, he wouldn’t have gotten shot because he would have been playing ball, his teenage pals said.
