He will be sentenced 10 a.m. June 6.
His 2019 superseding indictment alleged he committed the offenses against six children ranging in age from 12 to 15 in June 2019.
Aiad-Toss formerly worked for an outside company as an emergency room doctor at St. Elizabeth Boardman Hospital but was taken off the schedule when the allegations surfaced in 2019.
Among the allegations in his indictment were that Aiad-Toss cocerced a child younger than 14 to “engage in a commercial sex act” on or about June 1, 2019. Other offenses are alleged to have occurred on other dates in June 2019.
Federal investigators said earlier that Ashland police contacted the FBI after the mother of a 13-year-old girl told authorities she and other juveniles met Aiad-Toss on the social media app Snapchat and that he paid them for sex acts.
