FLINT, MI -- A retired Genesee County corrections deputy is facing criminal charges after authorities say he assaulted an inmate with pepper spray at the county jail.

Gerald Joseph Parks was arraigned Tuesday, Oct. 28, in Flint District Court on charges of misconduct in office, misuse of a dangerous weapon and assault and battery.

Genesee County Sheriff Robert Pickell said his office began investigating Parks after a computer disk containing security video of the alleged assault was discovered by another deputy.

The incident happened in 2012, according to Pickell.

Pickell declined to identify the inmate involved in the incident, but he said he was lodged at the Genesee County Jail after his bond was not posted in a pending case. The inmate is no longer in the jail, he said.

The deputy who discovered the alleged attack was looking for a blank disk and discovered the recorded security video, according to Pickell.

Pickell said the inmate was not hospitalized for his injuries.

Parks, 53, of Davison, worked for the sheriff's department for 31 years, according to Pickell. He retired two years ago.

"Parks does not represent who we are," Pickell said.

He was released on a $10,000 personal recognizance bond.

"We look forward to our day in court," said Parks' attorney, Jay Clothier. "We'll let our talking happen in court."

He is due back in court Nov. 18. The charges carry a maximum punishment of five years in prison.
