KALAMAZOO, MI -- Deputies are searching for a man who was mistakenly released from the Kalamazoo County Jail just days before his sentencing date.

Kalamazoo County Undersheriff Paul Matyas said the improper release in August was due to a "clerical error," because Antonio Berry's paperwork was "confusing."

Matyas said that on one court document was written "time served," meaning Berry was to be released from jail. But if the deputy who released Berry would have dug deeper into the file, he would have seen there was another charge that Berry was being held on and that bond had been denied.

"We take the blame," Matyas said. But he said it's an easy mistake to make, given that the inmate's files from the State Court Administrative Offices are sometimes confusing.

"It would be nice to know this is page one of three or some indication to look further in the documents," Matyas said. "It's frustrating. I hate to see employees set up for failure."

Matyas said the deputy who released Berry is a "solid employee," but he should have looked deeper into the file.

Berry, 28, failed to appear for his sentencing in March on a resisting and obstructing a police officer conviction, stemming from a 2013 incident, according to court documents.

He was arrested on the warrant for failure to appear on Aug. 10 and also picked up additional charges of resisting and obstructing, possession of marijuana, and open intoxicants in a vehicle on that date.

Berry again failed to appear for his sentencing on the 2013 offenses on Sept. 9, after he was improperly released from jail.

Matyas said deputies are actively searching for Berry and believe they will find him soon.

"He's a local guy. He's around here somewhere," Matyas said.
