Authorities arrested a 20-year-old man in connection with a shooting that killed one person and injured another during homecoming weekend at Winston-Salem State University in North Carolina. Ziyaire Antonyo Spinks faces charges of murder, assault with a deadly weapon with intent to kill inflicting serious injury, and felony possession of a firearm on an educational campus, Winston-Salem Police Department said Sunday.

The shooting Saturday night killed Peyton Izaia Patterson, 19, and injured Alyssa Janae Ellerbee, 19, who was treated at a hospital and released. Officers responding after hearing shots fired around 9:46 p.m. found Patterson suffering from a gunshot wound and attempted life-saving measures, but he did not survive. Police said the shooting stemmed from an altercation between two groups and determined it was an isolated incident. Spinks was not a student at the university, according to Assistant Chief Jason Swaim of the Winston-Salem Police Department.

A separate shooting on campus about 36 minutes later injured two additional people. No arrests have been made in that case as of Sunday afternoon, Swaim said. Police stopped a vehicle related to the second shooting but provided no further details.

Court records show Spinks had two prior pending cases in North Carolina, including concealed weapon and marijuana possession charges from March in Randolph County, and an October indictment in Guilford County for felony conspiracy to commit robbery and robbery with a dangerous weapon. Spinks is being held without bond. The university canceled remaining homecoming activities scheduled for Sunday and made counseling services available to students and staff.
