Winston-Salem State University canceled the rest of its homecoming weekend after two separate shootings on campus left one student dead and three other people wounded, police said Sunday.

Officers responded to the first shooting around 9:45 p.m. Saturday and found a 19-year-old man with a gunshot wound. He died at the scene despite officers' attempts to render aid. Police said that shooting stemmed from an argument between two groups of people.

Two shootings, 36 minutes apart

A second shooting on campus roughly 36 minutes later wounded two more people. Investigators said Sunday it was too early to say whether the two incidents were connected. Police have charged Ziyaire Spinks, 20, with murder and related counts in the fatal shooting; he is being held without bond and was confirmed not to be a student at the university, according to WRAL's reporting on the arrests. A second person, 18-year-old Cequan Warren Brower, faces an affray charge connected to the first shooting.

The university placed its campus on lockdown immediately after the shootings before later allowing students to walk back to their dorms under police escort, according to the Washington Post's account of the weekend. All remaining homecoming events were called off, and the school said it is offering counseling services to students and will increase its law enforcement presence on campus in the coming days.

Chancellor Bonita Brown called the violence "senseless" in a statement to the campus community, saying the university is "shaken" by the weekend's events, according to WSOC-TV's coverage of the chancellor's remarks.

"SENSELESS. OUR COMMUNITY IS SHAKEN."

What's next: homecoming is one of the biggest annual draws for HBCUs nationwide, bringing back thousands of alumni, and the cancellation of this year's remaining events is expected to renew scrutiny of campus security during the weekend's large off-campus gatherings. Investigators have not said whether additional arrests are expected in the second shooting.
