In a chilling incident, onlookers decided to take video of a fatal stabbing at a strip mall near Oceanside High School in Nassau County, New York, instead of helping the victim.

On Monday, a group of teenagers who witnessed 16-year-old Khaseen Morris get brutally assaulted and stabbed in the chest, pulled out their phones and decided to record and share the video on social media rather than stepping in to help him.

According to Detective Lt. Stephen Fitzpatrick of the Nassau County Police Department, Morris died becuase of his wounds, after being taken to a hospital. 18-year-old Tyler Flach, who was responble for the stabbing, has been arrested and charged with second-degree murder.

"Kids stood here and didn't help Khaseen. They would rather video this event. They videoed his death instead of helping him," said a clueless Fitzpatrick at a press conference on Tuesday, not knowing what to make of the onlooking teenager’s behaviour.

Around 50 to 70 kids were present at the spot when the incident took place and several of them came forward with information related to the stabbing.

Oceanside School District Superintendent Phyllis Harrington asked the parents to talk to their kids about social media, in addition to using restraint and judgement, in a video that was put up on Thursday. She also said “while social media is a part of our culture and not going away”, it is also important how people use it.

She further cautioned students to refrain from spreading rumours on social media.

Nassau County Executive Laura Curran pleaded with residents to use their phones to help people who were in danger rather than using it for liks and shares.

According to Fitzpatrick, the incident was a prearranged fight over who a girl might be dating or hanging out with. The fight which took place outside the strip mall, boiled over, with the victim and his couple of friends being charged by six or seven males.

In the ensuing melee Morris was stabbed by Tyler Flach. According to a statement released by the police on Wednesday, Flach is set to be arraigned on Thursday.
