A former Knox County Schools custodian has been sentenced to six years after pleading guilty to soliciting minors to send him nude photos.

Dustin Lee Dotson pleaded guilty to three counts of solicitation of a minor to engage in certain sexual conduct, a class C felony, in Sept. 2016. 

Dotson was a custodian at Inskip Elementary School when he was arrested in June 2016 for asking a 13-year-old girl to send him nude photos. He was fired by the school district soon after his arrest.

After his initial arrest, Knoxville police said a grandmother contacted the department's Major Crimes Unit and said her granddaughter and one of her granddaughter's friends had been by Dotson to send him photos as well. The juveniles were 11 and 12 years old.

Dotson was sentenced Friday by Judge Steve Sword to one year of split confinement and five years probation. Once Dotson is released from jail, he will have to register with the sex offender registry.
