Multiple law enforcement agencies are working together in the stabbing death of a Binghamton University student Sunday night.
Police released photos showing the alleged killer leaving the residence hall.
19 year old Joao Souza, a freshman engineer, was stabbed around 10:30 pm in a residence hall.
The suspect reportedly ran from the area, and witness reports describe the attacker as a light-skinned male in dark pants and a dark Puma hooded sweatshirt.
Investigators have spoken to numerous people overnight, and say the attack was not a random act.
The university cancelled all classes on Monday, and offered counseling services to anyone who needs it.
Any information that would help in this case should be reported to Binghamton University Police at 607-777-2393.
