Tyler Flach convicted of murder in stabbing death of Long Island teen

LONG ISLAND (PIX11) --- Tyler Flach was convicted of murder Tuesday in the 2019 stabbing death of Khaseen Morris, 16, on Long Island.

Flach, 21, was also found guilty of gang assault, assault, and criminal possession of a weapon after a two-week trial in Nassau County. Morris was stabbed in the heart during a brawl near a Long Island school, prosecutors said.

“Khaseen Morris was a bright, funny and energetic young man who, at only 16, had his entire life in front him,” Nassau `County District Attorney Ann T. Donnelly said.

The deadly fight erupted after a large group of teens got out of nearby Oceanside High School, where Morris had transferred not long before his death.

Dozens were involved in the brawl, authorities said. Morris was targeted over jealousy for befriending a girl. Flach is “an associate” of the girl’s ex-boyfriend, who may have been jealous of Morris’ friendship with the girl, according to investigators.

Another teen, 17, suffered a broken arm and swelling to his head during the brawl, police said. Others sustained minor injuries.

Flach wasn’t the only one arrested after the deadly brawl. Others were charged with second-degree gang assault.

Six of Flach’s co-defendants have pleaded guilty to various charges. Defendant Haakim Mechan is awaiting trial, prosecutors said.
