An online predator hunter group, Oklahoma Predator Prevention, provided Pennsylvania State Police with information on a Butler man charged with sending inappropriate messages to a minor.

According to police, Tyler Andreas Gunthner, 33, was charged with felony counts of statutory sexual assault, corruption of minors, criminal use of a communication facility, sending explicit material, involuntary deviate sexual intercourse and aggravated assault. He was also charged with one misdemeanor count of indecent assault.

Gunthner believed he was speaking to a 14-year-old girl named Nikki through a dating app called Skout, according to an affidavit in the case. Gunthner was actually speaking to a member of the prevention group posing as a 14-year-old.

According to police, the conversations started July 27 and continued until Sept. 12.

The two eventually exchanged numbers and during initial conversations, Gunthner and Nikki sent clothed pictures of themselves, according to the affidavit. When Nikki sent her photo, he said she looked “super hot” and “sexy.”

Eventually, Gunthner sent nude photos of himself and descriptive sexual messages about what he wanted to do to her, police said. He also sent inappropriate videos.

Gunthner told her he was from Pennsylvania, but was visiting family in Oklahoma. He asked her if she wanted to meet up for sex and told her that she should come with him to Pennsylvania to stay with him forever.
