ROCK COUNTY, Wis. —

A Rock County mother is accused of killing her 14-year-old daughter on March 19.

Court documents say 41-year-old Tyiece Oninski admitted to the killing of Kuren Rein in the Town of Turtle.

According to the criminal complaint, Oninski said, “I murdered her to protect her from somebody else, period.”

The complaint says she later explained that she was protecting her daughter from Elon Musk.

“The risk of harm here is pretty localized to herself and the victim here. There’s no evidence that she poses a risk to the community at large,” defense attorney Matt Lantta said.

“When we’re talking about an unsolicited, unprovoked attack of slitting a 14-year-old girl’s neck, who happens to be her daughter, that does put the public at risk,” prosecutor Richard Jay Sullivan said.

Investigators say toxicology reports showed benzodiazepines, amphetamines and THC in Oninski’s system.

The criminal complaint does not explain why Oninski viewed Elon Musk as a threat.

Oninski is charged with first-degree intentional homicide. Her next court appearance is scheduled for April 14.

The court set a cash bond of $1 million.
