SENTENCED: 19-year-old man accused of raping six-year-old girl inside Menomonee Falls church

WAUKESHA COUNTY (WITI) -- A 19-year-old Waukesha man has reached a plea deal -- charged in connection with the sexual assault of a six-year-old girl in Menomonee Falls.

Austin Mucha pleaded guilty to a felony charge of third degree sexual assault.

He's accused of having sexual contact with a six-year-old girl on June 23rd, 2013 in Menomonee Falls.

The complaint filed against Mucha says officers were called out to the Falls Baptist Church for a report of a sexual assault. There, they spoke with Mucha, who told officers he was hearing voices, and those voices were telling him to ask a little girl to take her clothes off.

Mucha told police he had a little girl take her clothes off in the daycare room at the church. Then, Mucha said a woman entered the room, and Mucha said he got scared, and ran -- according to the complaint.

The complaint says Mucha told another another officer: "I raped her."

Mucha told police he hears voices that tell him to do things -- saying he's been hearing the voices since high school.

Police were able to take a look at surveillance video that showed Mucha entering the nursery room at the church, and running out the door after a woman entered about seven minutes later.

The complaint says police spoke with Mucha's grandmother, who informed them she had spoken with Mucha about the incident at the church, with Mucha telling her he had raped the girl.

In court on Wednesday, January 7th, Mucha was sentenced to three years in prison, with credit for 455 days served. He's been ordered to serve five years of extended supervision.

Additionally, he must receive sex offender treatment, and register on the state's Sex Offender Registry.

Mucha must undergo a mental health evaluation and follow through with treatment, and maintain absolute sobriety.

He's been ordered to have no contact with anyone under the age of 18, and no contact with the victim, her family and the church where the incident occurred.
