A 19-year-old high school student was stabbed on West 56th Street in Manhattan yesterday afternoon and later died at the hospital. Police suspect the violence was sparked by a fight between the girlfriend of victim Theodore Beckles and the girlfriend of another student.

According to WCBS 2, "It all started as a fight between two girls near the building that houses both the High School for Environmental Studies and Independence High School... One of the girls was with a group of guys. Friends said Beckles stepped in to protect his girlfriend, who is pregnant with his child. Beckles was stabbed, and his attackers took off."

The Daily News reports, "Other students soon joined in the fray, which moved down the block toward Tenth Ave. During the melee, one member of the opposing group knifed Beckles."

Beckles' friend told WCBS 2, "His girl was in a fight and he didn’t want her to get hurt because she’s pregnant, and so he’s trying to push her away and push other girls off of her and then stuff just happened." Another witness said, "He got stabbed twice in the chest from what I could see."

Police responded at 2:45 p.m. and found Beckles, 19, stabbed in the abdomen. Beckles was taken to the hospital and underwent surgery, but died in the evening. The investigation is ongoing and the police have not released any information about the suspect or suspects.
