SPARTANBURG, SC (WSPA) – Court records from Arizona reveal that Todd Kohlhepp, the suspect in the kidnapping of Kala Brown and disappearance of Charles Carver, has been convicted of kidnapping in the past.

Kohlhepp pleaded guilty to the kidnapping and was sentenced to 15 years in prison.

According to court records, Kohlhepp kidnapped and sexually assaulted a 14-year-old girl when he was 15-years-old.

He was living with his biological father in Tempe, AZ at the time of the kidnapping.

According to court documents, Kohlhepp forced the girl into his home and tied her hands and put tape over her mouth and sexually assaulted her.

In his ruling a judge stated of Kohlhepp, “at the age of 9, he was ‘explosive’ and ‘preoccupied with sexual content.’ He has not changed. He has been unabatedly aggressive to others and destructive of property since nursery school.”

He went on to say, “Twenty-five months of the most intensive and expensive professional intervention, short of God’s, will provide no protection for the public and no rehabilitation of this juvenile.”

Kohlhepp also had extensive counseling, including hospitalization, for his behavior in Georgia, court records say.

The court documents also include a psychiatric evaluation that say Kohlhepp destroyed his room with a hammer, destroyed other children’s projects, cloroxed a goldfish, shot a dog with a BB gun, was dismissed from the Boy Scouts because he was too disruptive, and shredded his own new clothes. The report also says his father made a statement saying the only emotion Kohlhepp was capable of was anger.
