Two college students say the high cost of tuition led them to rob a bank.

The men pleaded guilty to two charges of aggravated robbery and six charges of kidnapping. They face 20 years in prison when sentenced Dec. 27.

Andrew Butler, 20, a student at the University of Toledo, told Hamilton County Common Pleas Judge Steve Martin on Monday that tuition increases outpaced his scholarships and financial aid.

Christopher Avery, 22, a student at the University of Cincinnati, said he couldn't pay for summer classes after an internship at a grocery store fell through.

"I was strapped for cash," Avery said. "I thought I had nothing to lose."

Armed with guns and wearing masks, Butler and Avery made off with $130,000 from a crowded Valley Central Savings Bank in suburban Reading on July 17, said Assistant Hamilton County Prosecutor Brian Goodyear.

An attempt to rob a check-cashing business a day earlier was thwarted when the students couldn't get through the business' security system despite firing four shots at the bullet-resistant glass, Goodyear said.

The men were caught after trying to switch cars. A witness who thought they were acting suspiciously called police.

Both were being held in a county jail without bond.
