Rock County is reeling after a 14-year-old girl was found stabbed to death inside a Town of Turtle home on March 20, and a Beloit mother now sits behind bars, accused of killing her. Deputies say the woman called county dispatch herself, calmly admitted to the stabbing, and insisted she had acted to protect the teen. The victim has been identified as 14-year-old Kuren Rein, and the case has shaken the usually quiet community.
According to WMTV, a 13-minute call came into the Rock County communications center on the morning of March 20. The caller, later identified as 41-year-old Tyiece Oninski, told dispatchers she had murdered the teenager the night before. Deputies were sent for a welfare check to a home in the 2000 block of E. Gorton Street, where they found Rein dead from multiple stab wounds and recovered a knife and sheath nearby. When a dispatcher asked whether the girl needed medical help, the caller responded, “she’s dead, honey. She needs a hearse.”
What investigators say
Newly filed court documents outline what investigators say they found inside the house. Authorities report that Oninski had deep lacerations to her neck and wrists when they arrived. A partial bare footprint seen inside the home was later compared with her left foot, which appeared stained with what looked like blood. At the hospital, medical testing reportedly showed benzodiazepines, amphetamines and THC in her system, according to a criminal complaint reviewed by WBAY.
Family response
Relatives have identified the teenager as Kuren Rein and shared a brief public statement remembering her as kind, optimistic and deeply loved. Coverage from WMTV notes that a GoFundMe created to help with funeral costs had raised several thousand dollars by March 24. Local outlet WIFR has continued to track donations and messages of support as the community rallies around the family.
Charges and court timeline
Prosecutors have charged Tyiece L. Oninski with first-degree intentional homicide. She is being held in the Rock County Jail on a $1,000,000 bond, according to officials. Her next court appearance in Rock County is scheduled for April 14, while the sheriff’s office and the Rock County Medical Examiner continue their joint investigation. The charge, bond and court date are detailed in local coverage of the sheriff’s office news release and criminal complaint, including reporting from WBAY.
What officials say next
Authorities say more information will be released as detectives work through leads from the criminal complaint and the medical examiner completes a full review of the evidence. Investigators are asking anyone with additional details about the case to contact law enforcement. Local newsrooms plan to continue following developments closely; for ongoing coverage, see reporting from WIFR.
