Peekskill police says a breakup preceded the stabbing that left a 17-year-old boy dead.

According to police, 16-year-old LaTonya Fisher stabbed her boyfriend, Justin Woodward, in the back with a large kitchen knife at her Bohlmann Towers apartment Thursday night. Police say Woodward told Fisher he was leaving her and heading south.

Woodward?s friends are shocked by his death and the circumstances around it. They remember him as a quiet guy. Woodward lived in Peekskill before moving to Buchanan, where he attended Hendrick Hudson High School. Grief counselors helped students cope with the tragedy at the school.

?This is not your typical teen violence type of situation. This was very unfortunate, a young girl with a history of emotional problems in a breakup. A woman in a breakup situation with her boyfriend lashed out and stabbed him in the back with a knife," said Peekskill Mayor Mary Foster.

Fisher is charged with first-degree manslaughter and is being held on $10,000 bail. She is due back in court Jan. 7.
