A female airman stationed at a Wyoming military base was killed along with another person when a suicidal man opened fire on them, according to local police and a new report.

Airman Abigail M. Smith, 24, and Michael Tolar, 44, were killed when Brian Perkins, 46, shot them in the parking lot of the local Romero Park around midnight Tuesday, according to a preliminary investigation by the Cheyenne Police Department.

Perkins then fatally turned the gun on himself, authorities said in a statement.

The crime scene is about 3 miles from the Francis E. Warren Air Force Base, where Smith was stationed, Stars and Stripes reported.

“Our deepest condolences to the family and friends of those affected by this incident,” Col. Peter M. Bonetti, commander of the 90th Missile Wing stationed at the base, told the outlet. “Airmen and families define our Air Force, they are and always will be our top priority. Losing one is too many.”

Investigators are considering “personal relationships” as a factor in the slaying, police said in their statement.

Officer Kevin Malatesta, a spokesman for the department, told the Wyoming Tribune-Eagle that all three people knew each other but that cops are still trying to determine the nature of their relationship.

Cheyenne, Wyoming’s capital and most populous city, normally sees only three or four homicides a year — and this week’s incident already brings the 2019 total to four, Malatesta said.
