SIOUX FALLS, S.D. (KELO) — A former Sioux Falls dance teacher and coach – accused of soliciting a minor – is now believed to have had at least three young victims.

Kevin Thongvanh

New court documents say 30-year-old Kevin Thongvanh has been indicted on 14 charges, including solicitation of a minor, sexual contact with a minor and sexual exploitation of a minor.

New court documents say three teenagers testified in front of a Minnehaha County grand jury.
After hearing that testimony, the jury decided there is enough evidence for Thongvanh to face additional charges.

We first told you about the investigation last month.

The indictment includes new charges involving two more juveniles.

All of the alleged crimes happened between 2021 and 2023.

The case against Kevin Thongvanh came to light two weeks ago.
Court documents say that’s when the principal at Roosevelt High School reported a student had been receiving sexual messages and pictures from a dance instructor.

The affidavit says the victim met Thongvanh, 2 years earlier, when she was a 7th grader and he was an instructor at Champion Legacy Dance Academy.

The academy says Thongvanh stopped working there in the Spring. He was working as an assistant dance coach at Roosevelt High School when the allegations surfaced.

The school district says his employment ended the day the investigation started.

He was initially charged with 10 counts of solicitation of a minor, but police told us there could be more charges.

“We’ll have to see as this investigation unfolds, but there is a chance that there could be more victims,” said Sam Clemens, PIO.

Now, Thongvanh is charged with one count of sexual contact with a minor, while in a position of authority.
Court documents say it happened on August first and involved a second victim.

On July 1st, 2022, he’s accused of engaging in the ‘simulation of an activity that involves nudity’ with a third minor. Just days later he’s accused asking that same victim to take part in a sexual act.

All 14-charges are felonies. Thongvanh remains in the Minnehaha County Jail.
