A Michigan teenager has been charged with killing a 78-year-old woman in her sleep after he opened fire from a moving car when he mistakenly thought someone in her home had shot at his mother’s home.

Arion James Wagner, 19, visited his mother on January 29 and saw a bullet hole in her window, which made him angry. According to phone conversations recorded while he was in jail, someone told him to look for a house with red curtains to find the person responsible for shooting at his mother’s house, MLive reported.

He ordered his pregnant girlfriend, whom he had already assaulted and threatened to kill, to drive him around Jackson until he saw a home with red curtains, and he opened fire with a stolen gun as she drove by.

Unfortunately, Nora Luna, who was sleeping inside, had nothing to do with the gunshot at Wagner’s mother’s house, but his reckless action killed her anyway. She was shot in the head while she slept on her couch.

In addition to murder, Wagner has been charged with discharging a firearm from a moving vehicle causing death and felony firearms in Luna’s murder. He’s also charged with assault with intent to do great bodily harm, felonious assault, and domestic violence for the hours-long assault on his girlfriend.

In the attack on his girlfriend, he allegedly put a handgun in her mouth and threatened to kill her during an argument over the name of a prescription drug. He also beat her, strangled her, forced her to strip naked, and lay on her belly on the bed while he put a pillow on her head and pushed the gun into the back of her head. He also told her he would kill her, her family, and her unborn child.

She later had a miscarriage.

Wagner is due in court again on February 27. He is being held without bond.
