A former Iowa-based sports radio host has been indicted on federal charges after allegedly scamming multiple investors out of $1.5 million in a ticket resale scheme.

According to the Des Moines Register, Marty Tirrell, 59, faces six federal fraud charges for allegedly stealing over $1 million from at least eight people between 2016 and 2017. The indictment alleges Tirrell made agreements with investors that if they paid him money, he would buy and sell sports tickets and split the profits with them. While he paid the investors at first, he started to lie to the alleged victims and used their money on personal items or to pay back other investors, federal court records show.

Tirrell reportedly sent checks to investors and after they bounced, he would send the victims false wire transfer information, the Register notes. Additionally, he’s been accused of filing false debit card fraud claims in an attempt to pay back investors. According to investigators, he made 144 unauthorized debit card transactions from his account which totaled $82,733.74.

An FBI agent took Tirrell into custody on Wednesday and he was charged with one count of mail fraud and device fraud, as well as two counts of wire and bank fraud. On Thursday, he appeared in federal court for a detention hearing, where the judge ordered him to remain in Polk County Jail until space was available. He was accepted to a residential release facility, where he must avoid contacts with victims or witnesses of his case.

Tirrell’s lawyers, prosecutors, and family members negotiated his release conditions and the judge said he will have to live at the facility for as long as the U.S. Probation Office dictates.

This case follows Craig Carton’s verdict late last year; the sports radio host was found guilty by a jury in November on three counts of wire fraud, securities fraud, and conspiracy to commit fraud. Carton, who gathered $4 million to start a ticket-resale business but used the money to pay back gambling debts, faces up to 45 years in prison.
