This is another tragic and shocking case from Beloit, Wisconsin, involving a mother accused of killing her 14-year-old daughter. Tyiece Oninski, 41, faces first-degree intentional homicide charges after allegedly confessing over a 13-minute call to Rock County Sheriff’s non-emergency line on March 20, 2026. Here’s a structured overview based on the probable cause affidavit and court records:
Key Events and Confession

- March 20 call: Calmly told dispatcher, “I murdered my daughter… She’s dead, honey. She needs a hearse.” Requested ambulance for herself. Claimed she killed K.R. “to protect her from somebody else”—specifically naming Elon Musk, without explaining any connection.
- At hospital: Asked enthusiastically if her name was “all over the news yet,” disappointed when told no.
Crime Scene and Evidence
- K.R. found face-down in a pool of blood, feet toward door, arms under head—no defensive wounds. Right neck and wrist injuries.
- Black pocket knife and empty sheath nearby.
- Toxicology: Oninski had benzodiazepines, amphetamines, and THC in her system.
- Grandfather (homeowner) thought K.R. was at school.
Legal Status
