SYRACUSE, N.Y. (AP) — Police in upstate New York say they have arrested a teenager in connection to the fatal stabbing of a 19-year-old man last weekend.

Syracuse police said Tuesday that 18-year-old Keenan Davis is facing charges of manslaughter and criminal possession of a weapon.

Authorities say Davis stabbed Christopher Hickey in Syracuse early Sunday morning. A witness told police Hickey was trying to protect his sister from her boyfriend at the time.

Davis is scheduled to be arraigned Wednesday morning. It couldn't be determined if he has a lawyer yet.
