Police say a 19-year-old male died in Longwood Sunday after an apparent argument over a female.

They say the fight took place outside of what they believed to be the girl's apartment building, located on Simpson Street.

Officials say the teen who died is the ex-boyfriend of the girl.

Police say they responded to a report of someone assaulted with a knife in front of 985 Simpson St. around 6 a.m. Sunday.

When they got there, they found the 19-year-old with stab wounds, and an 18-year-old with one stab wound in his stomach.

EMS took both teens to NYC Health + Hospitals/Lincoln where the 19-year-old was pronounced dead. The 18-year-old, who is said to be the current boyfriend, is expected to be OK.

No arrests have been made yet, and the investigation was ongoing.
