The Dupont murders are featured on Episode 3 of ‘Unsolved Mysteries’

Unsolved Mysteries’ third episode, “House of Terror,” examines the horrific 2011 murder of the Dupont family. The family patriarch, Xavier Dupont, comes from a noble French family and was running multiple failing businesses in France. 

Xavier’s friends reveal that he was a good husband to his wife Agnes, and a loving father to his four children — Arthur, Thomas, Anne, and Benoit. But when the entire family abruptly went missing, friends and family insisted police check on their home. 

Eventually, the Nantes police found the graves of all four children, Agnes, and the two family dogs under the terrace of the Dupont’s home. But Xavier was nowhere to be found.

Xavier Dupont goes on the run after murdering his family

As shown on Unsolved Mysteries, after finding the graves, investigators determined that Xavier had killed his family by drugging them with sleeping pills and then shooting them with his father’s rifle. After the murders, Xavier was caught on multiple security cameras around France, withdrawing money from ATM machines, eating at restaurants, and staying at motels.  

Xavier was last seen on parking lot security footage, which put him near a Roquebrune-sur-Argens motel. He was seen carrying a large bag, which looks like it may contain a rifle. French authorities believe that Xavier either died by suicide or is on the run, but either way, he has never been found.

‘Unsolved Mysteries’ showrunner says Xavier DuPont may have been spotted in Chicago

In an interview with Variety, Unsolved Mysteries executive producer Terry Dunn Meurer said that the new Netflix series is generating a number of leads in the Dupont case. She also revealed that one fan may have spotted Xavier living in Chicago. 

“Xavier, we got the most interesting tip,” Meurer said. “Somebody was actually in Chicago, I think they were on Lake Shore Drive, and they heard this guy talking French and they looked at him and they had just seen the episode. They sent us a photo, and it really did look like Xavier. It was striking.”

Meurer said that she sent the tip to authorities, but can’t confirm if it’s really him or not. She adds that for his case, investigators will need a very “specific” lead.

“In the Xavier case, what we’re hoping for is that he’s remarried or he has a girlfriend or he lives next door to somebody or he has a coworker who absolutely 100% knows that’s him,” she added. “Xavier looks so much like so many other people. With Netflix’s global reach, if Xavier is going to be found, we’re really hoping that the Netflix audience will find him. If he’s alive, that’s the mystery.”
