JEFFERSON CITY, Mo.- On December 6, 2019, a Randolph County jury found John Matheis to be a sexually violent predator. Over the course of three days, the jury heard evidence of Matheis’s lengthy history sexually abusing both children and adults.
 
Matheis was convicted of sodomy and sexual abuse in 1994 in Randolph County for sexually abusing his six year old granddaughter. During the investigation related to sexually abusing his granddaughter, more victims came forward and disclosed sexual abuse that they suffered at the hands of Mathies. Matheis was sentenced to 25 years in prison for his 1994 offense, but when given opportunities on parole, his offending continued, even after participating in sex offender treatment while incarcerated. Each opportunity Mathies had on parole, he created another victim.
 
Matheis was charged with a new offense in Randolph County in 2014 and a new offense in Boone County in 2015. These cases were dismissed when Matheis’s parole was revoked, each time returning to prison. While serving his sentence in the Missouri Department of Corrections, another victim came forward, writing a letter detailing the horrific sexual abuse she suffered from Matheis when she was an eight year old girl.
 
The jury heard evidence from two licensed psychologists that described various conditions they diagnosed Mathies with, including antisocial personality disorder, and other specified paraphilic disorder, non-consent.
 
Additionally, they jury heard evidence from a third licensed psychologist who concluded that Matheis’s behaviors are unlikely to change. After the jury’s verdict, Judge Scott Hayes signed an order committing Matheis to the custody of the Department of Mental Health for treatment until such time he is safe to be at large.
 
The case was handled by Assistant Attorneys General Paige Wheeler and Jennifer Coffin with assistance from Paralegal Rebecca Sullivan and Investigator Carla Ramshead.
