Riverton stepfather who shot, killed 18-year-old stepson arrested, charged with manslaughter

Update, 6:18 p.m.

Charges have been filed against 46-year-old Joseph Lee. He is facing manslaughter charges after he allegedly shot and killed his 18-year-old stepson Tuesday.

According to the probable cause statement obtained by ABC4.com, Lee told police when they interviewed him that he was teaching his daughter how to use and operate firearms at the time of the shooting. He had two guns that he was showing her, one that was loaded and one that was not, and he told police that he mistakenly picked up the loaded gun and pulled the trigger. The gun fired, and the bullet hit the victim, who was sitting directly opposite Lee, in the head.

Through a search warrant, police obtained video from the home of the entire incident. According to charging documents, the video showed Lee sitting on the ground and the victim looking at the gun in Lee’s hand, as Lee described to police.

Police said that in the video, as the victim moved to sit down, the gun fired, and “the victim is seen dropping to the floor and is motionless.”

Reportedly, the video shows that Lee waited several minutes before performing CPR.

The probable cause statement also detailed why police decided to charge Lee with manslaughter. According to Utah code, manslaughter occurs when someone “recklessly” causes the death of another person.

Lee told police that he served in the United States Army as a Green Beret, and police stated that he had “extensive training in the operation and safe handling of firearms.” Army guidelines tell officers to use the acronym THINK when it comes to handling firearms, which police cited in their report:

• Treat every weapon as if it is loaded.
• Handle every weapon with care.
• Identify the target before you fire.
• Never point the muzzle at anything you don’t intend to shoot.
• Keep your weapon on safe and your finger off the trigger until you intend to fire.

The arresting officer wrote that he believed that Lee handled his firearm in a reckless manner, despite his training and experience, and caused the death of another person.
