They were looking for her estranged husband, a National Guardsman who they said had sniper training.
Robin Munis was shot in the head with one gunshot that came from outside the Old Chicago restaurant where she had been performing just after midnight, Cheyenne police Capt. Jeff Schulz said. No one else in the restaurant was hurt.
Witnesses saw her husband, David Munis, in the area, but no one has reported seeing the shot fired, Schulz said. No weapon was found, but Schulz said investigators believe a rifle was used.
The couple had recently separated, and Robin Munis, 40, of Cheyenne, had complained about receiving harassing calls from her husband as recently as Friday, Schulz said.
"We are working solely on him being the suspect," Schulz said at a news conference. He described David Munis as "very dangerous."
David Munis, 36, is a second lieutenant in the Wyoming Army National Guard who is attached to the guard's training camp, according to guard spokeswoman Deidre Forster. Schulz said Munis received sniper training from the military, but Forster said she didn't know whether he did.
