Teen arrested, charged with murder in fatal Oceanside brawl over a girl

OCEANSIDE, NY — Police arrested a teen Wednesday in connection to a fatal stabbing in Oceanside.

Tyler Flach, 18, (left) was arrested for allegedly killing Khaseen Morris, 16, (right) during a brawl in Oceanside, Long Island on Sept. 16, 2019.

Tyler Flach, 18, was charged with murder in the second degree.

Khaseen Morris, 16, was fatally stabbed in the chest Monday. Police rushed to the strip mall on Brower Avenue after receiving 911 calls about a large group of teens fighting around 3:45 p.m.

The fight erupted after a large group of teens had gotten out of nearby Oceanside High School, where Morris had just transferred this school year.

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

Flach, who is a first-year college student, carried out the fatal stabbing, according to police.

“There’s got to be about 50, 60, 70 kids here,” said Detective Lt. Stephen Fitzpatrick, the commander of the Nassau County Police Homicide Division at a news conference at the crime scene on Tuesday morning. “We have a handful of kids that have come forward who have identified people involved in this.”

Police are asking anyone involved or anyone who witnessed the incident to come forward.

Another teen, 17, suffered a broken arm and swelling to his head during the brawl, police said. He was also hospitalized.

Flach is scheduled to be arraigned Thursday. He faces 25 years to life in prison.
