Police are searching for a 17-year-old they believe is responsible for the stabbing death of a Brooklyn man named O’Shea Sibley. The 28-year-old man was fatally stabbed at a Brooklyn gas station Saturday night in what police are investigating as a possible anti-gay hate crime. Sibley’s friend Otis Pena conducted a Facebook Live where he said that O’Shae Sibley was dancing – vogueing – to a Beyoncé song with friends at the gas station when a group of men approached them and started to shout gay slurs at them. The anti-gay slurs eventually led to a dispute. Pena, who witnessed the incident, said the argument escalated and one man stabbed Sibley. Pena said he went to Sibley’s aid and put pressure on his wound. Police said Sibley was stabbed in the torso. He was taken to Maimonides Medical Center, where he was pronounced dead. Sibley was a professional dancer who was featured in several music videos and also performed at New York City’s renowned Lincoln Center for the Performing Arts. Brad Hoylman-Sigal, a New York state senator, tweeted about the incident Monday, saying he was “heartbroken and enraged” to learn about Sibley’s death.
