The driver's knock on the door and inquiry about what was going on may have interrupted the alleged sexual assault of a young victim.

What a delivery driver heard may be integral to rape charges filed against a lake area doctor, according to documents released by the Camden County Associate Circuit Court.

The documents report a delivery driver was making a stop at a residence in Camden County when he allegedly heard screaming coming from inside the house. The driver’s knock on the door and inquiry about what was going on may have interrupted the alleged sexual assault of a young victim.

George A. Koch, 47, of Linn Creek was arrested on July 27, 2017 and charged with one count of first degree rape or attempted rape and first degree sodomy or attempted sodomy, unclassified felonies. In addition, Koch was charged with the Class E felony of incest and two class D felonies for statutory rape and statutory sodomy in the second degree.

According to the probable cause statement filed on July 28, 2017, the alleged sexual assault occurred on April 13, 2017 after a series of inappropriate conversations and progressive, illegal touching.

The vicim underwent a forensic child interview on July 25, 2017 by a Camden County detective at the Child Advocacy Center in Springfield and told investigators of the alleged crimes that had been committed by Koch.

Around Easter Break, the victim told detectives that she was showering in the basement of an unidentified residence when Koch approached her in a bedroom closet and carried her to a bed.

According to the court document, Koch undressed the victim, held her down and raped her. The victim described the alleged acts and used anatomically correct drawings to describe the effects of the trauma.

The victim stated this incident stopped when someone rang the doorbell and Koch went upstairs to answer it.

“[Redacted] stated she heard Koch talking to a delivery guy. [Redacted] stated the guy heard screaming and asked Koch what had happened,” according to the probable cause statement. “[Victim] stated Koch told him it was [redacted] not getting her way and brushed it off.”

After the alleged assault, the victim stayed downstairs and Koch stayed upstairs. The victim stated Koch was wearing a blue shirt and shorts.

The driver was later identified by detectives and stated that he remembered making the delivery to the residence, an area he had been delivering to for 12 years.

“[Redacted] stated he could hear the scream through the front door, but couldn’t remember if it was before or after he knocked,” according to the statement. “[Redacted] stated he yelled through the doorway and was confronted by the home owner, identified as Koch.”

The driver stated Koch was wearing shorts and a blue shirt. Koch is being held on a $20,000 cash bond or $100,000 surety.

According to CaseNet.com, Koch was officially charged on Friday, July 28, 2017 by Camden County Assistant Prosecutor Heather Miller. The bond conditions state the defendant shall be monitored by GPS tracking and avoid firearms or weapons.

The defendant was ordered not to have any contact with the victim and also states the “defendant shall comply with all conditions for alcohol and drug charges.” Koch was ordered to random urinalysis for drugs and alcohol while on bond.

On Friday, July 29, 2017, Attorney Tim Cisar requested MOCAM on behalf of the defendant for supervision. Judge Aaron Koeppen has been assigned to the case.
