An altercation over a girl led to a 13-year-old boy allegedly stabbing a 17-year-old to death in New York.

The accused 13-year-old turned himself in along with two other teenagers, police said.

The victim, Nyheem Wright, was allegedly chased after by the assailants and stabbed in a Coney Island parking lot in Brooklyn on Jan. 20 at around 3:20 p.m., according to ABC7NY.

The encounter was reportedly spurred by a fight that took place between two girls the previous day.

It is believed Nyheem was standing up for a girl when the 13-year-old and his friends turned on him and chased after him for several blocks. The suspect, who had a large knife underneath his armpit, allegedly stabbed Nyheem in his torso right in front of his twin brother.

The victim was rushed to the hospital but succumbed to his injuries the next day.

The 13-year-old was with his mother when he turned himself in and eventually confessed to stabbing the victim. He was charged with second-degree murder and fourth-degree criminal possession of a weapon in connection with the attack.

The other two teens aged 14 and 15 were charged with assault and gang assault.

All three teenagers have had previous run-ins with cops. The 13-year-old has at least one prior arrest for assault as a juvenile, the 15-year-old has at least eight previous arrests as a juvenile for assault, burglary and grand larceny, and the 14-year-old has been arrested for two previous robberies, police said.

Nyheem's mother Simone Brooks told the New York Post that his twin brother, Raheem, "stayed with his twin brother the whole time."

Raheem tried to help his brother as he died right before him, the mother said.

"I was on the phone with [Raheem] ... and when the ambulance came, they kept saying, '[Nyheem's] losing a lot of blood, he's losing a lot of blood!'" Brooks previously told the outlet.

Before the three teens were charged for Nyheem's killing, the mother said she wanted to see the "little punks" pay.

"These ones nowadays, they all want to pull weapons," she said at the time. "They don't want to fight it out because they're just little punks."

"We want justice for my son Nyheem because he did not deserve this, and we are not OK," Brooks added.
