Two University of Wisconsin-Platteville students were found dead from gunshot wounds in a campus residence hall on Monday, just days after the school’s commencement ceremony, university officials say.

The university police department revealed Tuesday that the students were Kelsie Martin of Beloit, Wisconsin, who died from a gunshot wound after being transported to a hospital, and Hallie Helms of Baraboo, Wisconsin, who died at the scene from a self-inflicted gunshot wound, preliminary autopsies showed. Both women were 22.

“No other subjects are suspected to have been involved in the incident,” a university statement said Tuesday. “Further investigation continues around the circumstances surrounding the death of the two individuals.”

UW-Platteville Police Chief Joe Hallman said his department received a 911 call around 4 p.m. local time Monday about an incident at Wilgus Hall, a residential building on campus. Upon arrival, they determined it was an “isolated incident” that posed no “active, ongoing threat,” he said at a press conference.

Martin was the assistant resident director at Wilgus Hall, where Helms was a resident. The Milwaukee Journal-Sentinel reported that Martin had just graduated summa cum laude with a degree in psychology, and Helms had just graduated magna cum laude with an elementary education degree.
