Ethan Holt

As for Holt -- he was arrested on October 28th, 2014 after detectives with the Waukesha Police Department learned he allegedly communicated with, met and sexually assaulted a 12-year-old girl who lives in Waukesha on more than one occasion.

Authorities say the suspect used social media smartphone apps to communicate with the victim. The apps used were: Tinder, KiK, text messaging, Whisper and Snapchat.

Waukesha police say the suspect “groomed” the victim and sent nude pictures to her through these apps.

Waukesha Police Sergeant Jerry Habanek said the girl and her parents contacted police -- telling investigators that she and Holt had sex in his vehicle near the Waukesha Public Library after initially meeting online.

Prosecutors say the girl's photos showed her without clothing, and Holt's pictures displayed his genitals.

The document also indicates Holt asked the girl about being bisexual, and about having a threesome with one of her friends.

"Ethan Holt used the username, or profile named called 'probablyinthegym' to communicate with our victim. He also indicates in some of his chats with other people that he has done this before, that he has had sex with young victims before," said Habanek.

Sergeant Habanek said the girl told Holt that she was 13 years old and the complaint alleges he took to the internet to brag about "taking a 13-year-olds." It is believed that he was referring to the girl's virginity.

"The girl appeared that she was groomed to think that this was okay," said Habanek.

Matter will be in court on March 11th for a restitution hearing.
