Update (September 30, 2019):  Police have arrested and charged several more teens with gang assault in connection to the fatal stabbing of a Long Island teenager, ABC7 reported.

Khaseen Morris, a 16-year-old teen, was stabbed outside of a pizza shop in Oceanside, New York. A video of the event circulated on social media, showing Morris being stabbed. Tyler Flach, 18, is one of the teens accused of fatally stabbing Morris as other teens stood by and even recorded the altercation, CBS New York reported. 

According to authorities, the two agreed to fight at a New York strip mall after school because Morris was allegedly spotted with another teen’s girlfriend. Once Morris arrived, other teens from a neighboring school district surrounded him while he was being stabbed in the chest. 

Flach has pleaded not guilty to manslaughter charges. The other teens have either surrendered to the police or were taken into custody as part of the investigation.

Although police said none of the teens are a part of a gang, they were charged with gang assault for the nature of the attack, ABC7 reported.

Described as a free-spirit, Morris was a skateboarder who donned half-red, half-Black dreadlocks and had an inclination for the arts, the New York Times reported.

His funeral will be held Saturday in Oceanside.

Original: As family and friends are still mourning the disturbing stabbing of their loved one, 16-year-old Khaseen Morris, police have arrested a white teen in connection to his death. 

Video of a lethal brawl outside of a pizza shop in Oceanside, New York, circulated on social media, showing Morris reportedly being stabbed by 18-year-old Tyler Flach, as other teens stood by and even recorded the altercation, CBS New York reported. 

According to authorities, the two agreed to fight at the New York strip mall after school because Morris was allegedly spotted with another teen’s girlfriend.

Once Morris arrived, other teens from a neighboring school district surrounded him while he was being stabbed in the chest. 

Upon viewing the video, police apprehended Flach, charging him with second-degree murder.


Keyanna, Morris' sister, said he was “amazing” and that “everyone loved him and he loved everyone.”

She described the details surrounding her brother’s death.

“The girl wanted him to walk her home and he was like okay. This girl played a game and tried to get her ex-boyfriend jealous and said, 'Somebody else walked me home.'”

Described as a free-spirit, Morris was a skateboarder who donned half-red, half-Black dreadlocks and had an inclination for the arts, the New York Times reported.

Despite their six-year age difference, Morris' older sister, Kedeemah, 22, said she thought of her brother as her twin. The two had previously got matching tattoos dedicated to their favorite rappers, Lil' Peep and XXXTentacion. 

"He danced, he was very funny," she said.

Nassau County Police Lieutenant Stephen Fitzpatrick said he is disgusted that so many people stood by without helping Morris. 

“They videoed his death instead of helping him,” he said. “This can't go on. Your friends are dying while you stand there and video it. That's egregious.”

Before Flach’s arrest, police asked the teens who were present during the brawl to come forward. 

“If you are not a part and parcel of the murder of Khaseen Morris, now is the time to get in touch with us and let us know who did this and why,” Fitzpatrick said.
