Racine police say a 36-year-old registered sex offender is back behind bars after he went to a 15-year-old girl’s house to have sex with her.

David Greeno, of Racine, was charged Friday in Racine County Circuit Court with a single felony count of using a computer to facilitate a child sex crime. If convicted, he faces up to 40 years in prison and/or $100,000 in fines.

According to the criminal complaint, Greeno had an appointment last month with his parole officer, and she discovered sexually explicit messages on his cell phone with a 15-year-old girl through the Fast Meet app. During several conversations, the girl admitted she was 15, and Greeno asked if she was okay having sex with a man in his thirties. She also gave Greeno her address.

Police say the parole officer reported the conversations, and they made an appointment to speak to the girl with her father present. She admitted to having the conversations and said Greeno came over to her house, but he didn’t come inside.

A search warrant for Greeno’s phone revealed several conversations with people ages 13 to 60 located all over the country, the complaint reads. Greeno was back in custody Sept. 8 for failing to keep his sex offender registry updated and told investigators he was only playing around with the girl but admitted he knew she was only 15.

Greeno was assigned a $15,000 cash bond at his initial appearance Friday. He will next be in court Nov. 2 for his preliminary hearing.
