Woman didn't know gun was loaded, shoots and kills boyfriend

20-year-old Makenzie Halinski was at her boyfriend's house in Festus, Missouri. She and her boyfriend, 20-year-old Cole Campbell were in the basement smoking marijuana and drinking. In a police interview, Halinski said that Campbell was showing her how to use guns and that he would always unload a gun and put the safety on before handing it to her.
At some point, Campbell handed Halinski a handgun and told her it was unloaded and the safety was on. He told her to point the gun toward him and said "shoot me." Thinking the handgun was empty, Halinski pulled the trigger.

The gun discharged and Campbell was shot in the forehead. Campbell was declared dead at the scene.
Neighbors said they were not surprised, that Campbell had set up a shooting range in his basement and that at times he practiced shooting targets from his basement bed.
Police seized multiple guns as well as several pipe bombs from the house.
Halinski was charged with involuntary manslaughter.
