A Monroe County man who works as a special agent for the Illinois State Police was arrested by Monroe County Sheriff’s Department deputies following a domestic incident that occurred late Wednesday night at his residence on Old Red Bud Road south of Waterloo.

Pete M. Goodman, 38, of Waterloo, has been charged with aggravated domestic battery, a Class 2 felony, for “intentionally strangling” his girlfriend during the incident, court information alleges. Goodman has also been charged with felony unlawful restraint for allegedly slamming a 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,” according to court information.

Goodman posted bond and was released from county jail with a preliminary hearing date set for Jan. 3.

Illinois State Police Director Hiram Grau issued a statement Thursday afternoon in response to Goodman’s arrest.

“The allegations against Special Agent Goodman are disturbing to the Illinois State Police and the citizens we serve,” Grau said. “ISP officers are expected to serve the citizens of Illinois with integrity, service and pride.”

Grau said the ISP will cooperate fully with the criminal investigation being conducted by the sheriff’s department, and “a prompt and thorough administrative investigation is already under way.”

“Goodman has been relieved of all police powers pending the outcome of these investigations,” Grau added.
