Maine Mom Stabbed To Death By Teen Son And Friends Over Stolen Marijuana

Lukas Mironovas, 16, pleaded guilty to murder and conspiracy to commit murder in the April 2018 death of his 47-year-old mother Kimberly Mironovas. The Maine teenager and his two friends killed his mother after she confronted them about stealing her marijuana.

Lukas was sentenced to 33 years in prison Thursday. Prosecutors alleged Lukas, then 15, and his two friends William Smith, then 15, and Thomas Severance, then 13, plotted to kill his mother after she came home from beauty school and accused them of stealing some of her marijuana, then refused to give Smith and Severance a ride back to Massachusetts, where they lived.

Lukas Mironovas’ defense attorney Pamela Ames told PEOPLE, “First, they were going to steal the car and drive themselves to Massachusetts. But they discarded that because she would be able to find her car and they would get caught.”

The teens next course of action was to drug her wine with prescription pills and slit her wrists to make it look like a suicide, but decided against that plan because the pills didn’t dilute sufficiently. “Then they come up with the plan they will strangle and stab her and stage it to look like a suicide or a home invasion, and she got killed in that,” Ames says.

According to the publication, Ames says Lukas allegedly backed out of the plan when his mother told them she would go ahead and drive the two teens back to Massachusetts. She said Severance allegedly followed through with not participating in the murder.

“It was Mr. Smith who was the ringleader,” Ames said. “He was the one who wanted to go through with it, no matter what.” Prosecutors said fifteen minutes after Kimberly went to bed, Smith, and Lukas snuck into her bedroom and choked her. Lukas then repeatedly stabbed her in the neck, which was Kimberly’s cause of death according to the medical examiner.

Severance, 14,  pleaded guilty to conspiracy to commit murder in the homicide and is incarcerated at the Longcreek Youth Development Center until the age of 21. Smith, 17, pleaded guilty to murder and conspiracy to commit murder and was sentenced to 28 years in prison. He is serving time at Long Creek until he turns 18 and then will be transferred to Maine State Prison for the remainder of his sentence.
