A Butler man was sentenced Thursday to serve up to two years in prison after pleading guilty to sexually assaulting a 17-year-old autistic girl in April 2025.

Ivan Cumba, 55, was sentenced to serve from 12 months minus one day to 24 months minus two days in the Butler County Prison followed by 48 months of probation; including serving the first three months on house arrest with electronic monitoring after pleading guilty to a felony charge of aggravated indecent assault.

Judge Maura Palumbi said Cumba’s conviction counts as a tier 3 offense under the Sex Offender Registration and Notification Act and requires him to register with state police for the rest of his life. She also ordered him to follow the county adult probation office’s requirements for sexual offenders.

Cumba did not address the court or the victim’s family before the sentence was imposed.

Butler police filed charges against Cumba following an April 26 incident at a Fourth Avenue home. Cumba arrived unannounced at the home and spoke with a woman he had known for years. While the woman was in a bathroom, Cumba went to awaken the girl who was asleep upstairs. The woman reportedly told police Cumba’s behavior was not unusual.

Police said the woman exited the bathroom after a short time, went to the girl’s room and found the door closed, which she said was uncommon. The woman entered the room and saw Cumba sitting on the bed next to the sleeping girl with his hand under her blanket inside her underwear before she began shouting at him. The woman was able to get Cumba out of the house before calling 911.

The mother of the now-19-year-old woman didn’t speak in court. However, after the sentencing hearing, she said she believes Cumba should have been sentenced to serve many years in state prison. She called the sentenced he received a “slap on the wrist for what he did.”

Her daughter was 17 at the time of the assault, but mentally she was like a 7 or 8 year old due to her autism, she said.

She said Cumba was a family friend for 20 years and her daughter thought of him as her uncle before the incident.
