XENIA — A man was sentenced Friday to serve 18 months in prison in relation to several thefts at Wright State University in 2015. Mark Coleman, 24, was sentenced for three cases and seven charges – all either grand theft of a motor vehicle or receiving stolen property charges – in Greene County Common Pleas Court.

According to information from Wright State spokesman Seth Bauguess, Coleman, who was not a student, would go into campus buildings “looking for people who had left their keys out on a desk … wherever keys could be found, and he was just grabbing [the keys] if he could,” he said.

Bauguess said Coleman would then go into nearby parking lots on campus and use the remotes to locate the associated car.

Coleman’s attorney, Michael Booher, said he was pleased with the outcome.

“Hopefully we tied up all the cases that were coming out wherein he was a suspect,” he said. “My hope is that after he spends a little time in an institution that he won’t reoffend.”

In December of 2015, Coleman was indicted on eight charges related to the thefts of two vehicles, a bank card and a credit card in 2015, according to court documents. As part of a plea agreement, Coleman pleaded guilty to five of the charges and was sentenced to 18 months in prison.

Earlier this week, Coleman was indicted on an additional receiving stolen property charge for thefts in December of 2015. Coleman pleaded guilty to that charge Wednesday and was sentenced to 12 months in prison Friday.

Coleman was also indicted Thursday on two charges related to the thefts of two additional vehicles in January and November of 2015. He pleaded guilty to those charges Friday and was sentenced to 12 months in prison.

Coleman will serve concurrent sentences for all the charges. He could have faced up to 15 years in prison if convicted of all the charges.

“We had the opportunity to work out an arrangement where he would do one sentence for everything, so I figured it was in his best interests to get that done,” Booher said. “He didn’t have an illusions about avoiding jail time. The state did their homework. There was either admissions or DNA evidence that linked him to all the vehicles, so it wasn’t the case where it made sense to go to trial.”

Coleman was sentenced to five years of probation in 2013 for two vehicle thefts at Wright State, according to court records.
