A teenage girl in Indiana is accused of falsely claiming sexual assault after she alleged a boy she met for a consensual sex act had raped her.

According to WTHR, 19-year-old Maggie Wallace of Pendleton reported that she had been sexually assaulted at Mounds State Park in July.

Initially, Wallace told police that a man had come up behind her while she was jogging in the park, tossed her to the ground and assaulted her. Presumably, the story may have appeared to be somewhat credible,  as a witness had seen the presumed attack and called 911. Wallace told police she was able to fight off her attacker.

But an investigation found that Wallace had actually met her so-called “attacker” on the “whipser” app, and set up a consensual meeting to act out a rape fantasy.

It is unclear what led investigators to question Wallace’s initial story and pursue credit card information that led them to a 17-year-old boy who said he made arrangements with Wallace to meet in the park that day.

“The juvenile claimed he responded to a post from the female who was looking for someone to fulfill a ‘rape fantasy,’ ” Madison County Sheriff Scott Mellinger told the Herald Bulletin.

The teen boy reportedly had screenshots of messages to back up his story.

“Maggie Wallace initially denied the new information but ultimately admitted she didn’t tell investigators the truth when she filed a report of being sexually assaulted,” Mellinger said.

Wallace is currently being held at the Madison County Jail on $3,000, according to the most recent report.
