(NewsNationNow) – A Tennessee mom is accused of luring at least nine teen boys on social media into having sex with her.

Investigators say Melissa Blair, 38, traded items for sexual encounters with male students who attend McMinn Central High School. She even had one of her own kids enrolled in the district; that child is now transferred.

“They’re still asking for more victims to come forward,” Bo Williams, an anchor for NewsNation affiliate WATE in Knoxville, said on “Dan Abrams Live.”

McMinn County Director of Schools Lee Parkison said the investigation began after an anonymous letter was left in his office.

“Without them, this could still be going on,” Parkison said, thanking whomever wrote the letter.

Parkinson said Blair was not employed by the school but was involved with school clubs, “… like other parents are.”

The encounters happened from spring 2020 through late 2021, officials allege. Sheriff Joe Guy said two of the students have since become adults.

“The superintendent, noting that in this day and age of social media … was somewhat shocked that we didn’t have any red flags leading up to this, any type of alerts,” Williams said.

Blair is charged with 18 counts of aggravated statutory rape, four counts of human trafficking by patronizing prostitution and one count of solicitation. Her indictment showed a vehicle had been confiscated.

When asked about the reaction from the community, Williams said “they’re just in some disbelief right now.”

Blair is currently free on $100,000 bail. Her arraignment is scheduled for February 28. The county school system has banned her from school property and activities.
