Cops: Man had conversation with Plain store clerk before robbing him

December 24, 2018

Authorities say a Madison man chatted up a village of Plain gas station clerk earlier this month before claiming to have a weapon and demanding cash.

The Sauk County District Attorney’s Office last week filed a charge of felony robbery with threat of force against 49-year-old Douglas D. Dederich. If convicted, he faces up to 15 years in prison.

Prosecutors say a man – later identified as Dederich – made small talk with the employee behind the counter of the Quik Stop gas station on Dec. 8, asking for directions before purchasing some cigarettes and snacks.

The man then used the bathroom. When he returned, he struck up another conversation with the clerk about Wisconsin Badgers football, at one point falsely claiming he was on the 1988 roster, according to the criminal complaint.

After that, prosecutors say, the man claimed he had a weapon, placed a blue grocery bag on the counter and had the clerk fill it with cash.

The robber fled the scene, and police who responded to the store later circulated an image of him taken from a gas station security camera on social media.

Investigators later received information from a woman who said she was certain the person in the surveillance image was Dederich, her estranged husband of 30 years.

Local authorities later got word from the Madison Police Department that Dederich had been arrested in relation to different burglary.

In an interview with investigators, Dederich allegedly confessed to the burglaries and said his routine was the same. He “walked in, talked to him,” and added that “You know, I don’t know why I wasted time talking to people.”

Dane County prosecutors have charged Dederich with the Nov. 28 armed robbery of an auto repair shop and the Dec. 3 armed robbery of a different gas station.

Dederich told investigators he has a drug addiction, and apologized. He has been jailed on a $3,500 cash bond and is due to appear in court Wednesday.
