Teenage Son First Tries To Kill Mom With Pills, Then Strangles And Stabs Her, Police Say

First, the boys tried a gentle approach. They’d dissolve pills into mom’s wine and kill her like that.

Only one problem: the pills didn’t dissolve. So, they came up with another plan - they’d strangle and stab her to death while she slept.

That’s the picture court documents paint of the murder of Kimberly Mironovas, 47, who was found dead in her home in Maine around 2 A.M. on Sunday, according to CentralMaine.com.

Her son, Lukas Mironovas, 15, and his friend William Smith, 15, were both charged with murder and conspiracy to commit murder.

Kimberly Mironovas had just moved to Maine to get new start. She sold her condo in Massachusetts and enrolled in cosmetology school, Anthony Coco, president of Aveda Institute Maine, told Oxygen.com. She was happy to be doing hair, he said, and learning a new career. She left her old neighborhood to get her son away from "the city life."

The day before her murder, Kimberly Mironovas was cutting hair at the school when she received an emergency call about her son. He'd allegedly built an illegal bonfire at her home in Litchfield, a small Maine town with a population of about 4,000.

"In the last few weeks I think it must have been getting bad with her son," Coco said on Wednesday. "She was talking more to the teachers, and dealing with a lot. One day she came in and she was pretty rattled, and she had commented that she was afraid of him."

The day of the bonfire was the same day the teens planned the murder, court records said.

“After the crushed medication failed to dilute sufficiently in liquid, Thomas Severance, William Smith and Lukas Mironovas discussed causing Kimberly’s death by other means: stabbing and strangling her,” the petition stated.

That's when her son Lukas Mironovas put on a mask and gloves and armed himself with a knife. He and Smith went into the mom's bedroom while she was asleep, records say, and strangled her. The son also allegedly stabbed his mother in the neck.

An old neighbor in Massachusetts told the Boston Globe she saw Smith and Lukas Mironovas on April 15, when Lukas Mironovas came to visit.

“They were talking about video games and stuff like that. Nothing particular stuck out in mind. He just looked like a normal 15-year-old,” she told the Globe. “The last thing [Lukas Mironovas] said to me was, ‘Thank you so much for the ride.’ I mean what kind of kid who has manners like that does such a thing?”

The prosecutor in the case, Assistant Attorney General Meg Elam, told CentralMaine.com that they planned to try the boys in adult court. In order to do so, they needed to complete mental health competency evaluations, which would take some time.

The spokeswoman for the Attorney General’s Office in Maine, Melissa O'Neal, told Oxygen.com that the boys were being held at the Long Creek Youth Development Center in South Portland, about an hour away from the murders.

It’s not clear who notified police about the slaying.
