An Illinois State Police officer was charged Thursday with aggravated domestic battery and unlawful restraint by the Monroe County State's Attorney's Office.

Pete M. Goodman, 38, of the 6000 block of Old Red Bud Road in Waterloo, is accused of choking his girlfriend, Audrey Lloyd, Wednesday.

Goodman also is accused of preventing Lloyd from leaving his house, court documents state, by "slamming the car door shut, grabbing and dragging her back to the residence, slamming her head into the side of the residence, then throwing her on the living room floor and taking her pants off."

Goodman pleaded not guilty to the charges. He is due in court Jan. 3.

Goodman could not be reached for comment Thursday. An attorney for Goodman was not listed in court documents.

Illinois State Police Director Hiram Grau released the following statement: "The allegations against Special Agent Goodman are disturbing to the Illinois State Police and the citizens we serve. Illinois State Police officers are expected to serve the citizens of Illinois with integrity, service and pride. The charges against Special Agent Goodman are an accusation, and he is presumed innocent unless proven guilty."

State police are cooperating with the Monroe County Sheriff's Office and an administrative investigation is under way, Grau said.

Goodman was relieved of all police powers pending the outcome of these investigations, Grau said.

It was not clear Thursday if Goodman is on paid or unpaid administrative leave.

"The administrative details are still being finalized," said Monique Bond, state police spokeswoman.

Goodman has been employed by Illinois State Police for 12 years, Bond said.

Goodman faces a possible three to seven years in prison on the aggravated domestic battery charge, and one to three years in prison on the unlawful restraint charge.

Bail for Goodman was set at $25,000, on the condition that he have no contact with Lloyd.
