The Illinois State Police confirmed to Fox News Digital that the young victim, identified as Kylie Toberman, met her untimely death in the town of Vandalia. Her biological mother, Megan Zeller, provided her daughter’s identification.

Following the incident, Arnold Rivera was apprehended and is now facing serious charges, including first-degree murder, aggravated criminal sexual assault, and the concealment of a homicidal death, according to a spokesperson from the Fayette County Sheriff’s Office. The teenager had been reported missing the same day she was found.
