Officials with the U.S. Marshals Service and the Georgia Department of Corrections are trying to find a convicted felon after he was released from prison by accident, authorities said.

Tony Maycon Munoz-Mendez, 31, was convicted of rape and aggravated child molestation in Gwinnett County, according to Georgia Department of Corrections records. He was accused of assaulting a girl under the age of 10, Channel 2 Action News reported.

As he awaited his trial, Munoz-Mendez wrote the judge hearing his case a letter claiming he was innocent and saying he wanted to get back to his children, Channel 2 reported.

“I have no family here in the United States to help me out and I have to rely on myself on everything, and it’s hard,” the letter said, in part. “I know I’m innocent.”
