Crete police arrested Martynus Monday night. He was charged with indecent solicitation of a child, traveling to meet a minor and using the Internet to lure a child for sex.
Martynus is employed by the Will County Health Department as a mental health counselor who works with troubled children and also as a coach and referee for the Illinois High School Association, a police press release said.
He allegedly drove his vehicle to a fast-food restaurant, where he contacted an undercover officer via his smart phone and asked to meet to have sex, the release said. Martynus had just finished refereeing a basketball game in Beecher and was insistent on meeting the girl Monday evening.
A surveillance operation was initiated and Martynus was seen awaiting the arrival of the girl and exchanging text messages with her from his vehicle.
He was arrested without incident, and his vehicle and smart phone were seized, the release said. He allegedly confessed to initiating the meeting in an attempt to have consensual sex with the girl.
