LARAMIE, WYO. ? Three University of Wyoming students were found dead in a home near campus Sunday in what police said appeared to be a triple murder or murder-suicide.

A fourth student, who lived at the house, suffered superficial wounds and had yelled for neighbors to call for help, police said.

Investigators were treating the case as a triple murder, but were considering the possibility of a murder-suicide, Laramie police Commander Dale Stalder said. All the people involved were accounted for, he said.

“We just don’t have all the facts yet,” Stalder said.

The victims were Justin R. Geiger, 20, of South Beloit, Ill., and Amber N. Carlson, 19, of Denver, and Laramie resident Adam Towler, 20.

Geiger lived in the house, along with Anthony N. Klochak, 19, of Chardon, Ohio, who had yelled for help.
