When a teenage gunman confronted Dereck Chen and his three friends in an elevator of a Brooklyn BJ’s wholesale store around 10:15 p.m. on Thursday, the 19-year-old from Bensonhurst gave up his backpack.
But as the elevator reached the bottom floor, Chen had a change of heart and fought back against the armed bandit.
It was his last defiant act. Edino Tzul, 18, also from Bensonhurst, shot Chen twice in the face and shoulder at the Shore Parkway big-box store in Bath Beach, killing Chen, police say.
Tzul fled, as did Chen’s three friends, one of whom called 911.
In the melee, Tzul also robbed one of Chen’s pals, a 17-year-old, grabbing his wallet, airpods and speaker, said cops.
Medics rushed Chen to NYU Langone Hospital-Brooklyn, but he could not be saved.
After the slaying, Tzul made his way to the nearby Gravesend Bay shoreline, behind the BJ’s store.
Infrared camera footage captured by the NYPD Aviation unit shows what happened next as Emergency Service Unit officers confronted and arrested Tzul on the rocky shoreline.
In the video, Tzul surrenders with his his hands raised, and walks up the rocks toward toward the officers. One officer then pins him to the ground, where Tzul ended up in handcuffs.
Police recovered a 9mm handgun in the case. Tzul, who has no criminal record, was charged with murder, six counts of robbery, four counts of criminal use of a firearm and two counts of criminal possession of a weapon.
