The straphanger gunned down on a subway platform over the weekend has been identified as a 26-year-old from the Bronx.

Darell Rodriguez was shot in the chest at around 12:20 p.m. Saturday at the 53rd Street/7th Avenue subway station in Midtown Manhattan by an unidentified stranger who then fled the scene, the NYPD said.

Rodriguez is believed to have been heading home from work as a security guard at the front desk of a Manhattan building, according to sources.

He was waiting for a northbound E train to his home in University Heights in the Bronx when his killer approached him, displayed his gun, and shot him once, police sources told The Post.

The pair had a dispute on the platform, although details remain unclear, NYPD Deputy Chief Keith Shine said on Sunday.

The killer then left the station traveling northbound on 7th Ave., and is still on the loose, according to police.

He was last seen wearing a red tracksuit, a black vest and face mask, and carrying a backpack.

It is not clear whether the killer knew his victim, but police emphasized the shooting was targeted.

Rodriguez was transported to Bellevue Hospital where he was pronounced dead on arrival just after 1:00 p.m., police said.

Rodriguez’s shooting marks the seventh murder in the New York City transit system this year and the fourth gun death, up from two over the same period in 2025, according to NYPD statistics.
