Pam Hupp confirmed as shooter in O’Fallon home invasion; suspect ID’d


O’FALLON, MO (KTVI) – Police confirm Pam Hupp shot and killed a man she reported burglarizing her home. Hupp was a central figure in a highly publicized murder trial covered extensively by FOX 2.

Louis Royce Gumpenberger, 33, is the man O’Fallon police say died in that shooting. The Medical Examiner’s Office reports that it was very difficult to identify him. They didn’t know who he was, even early this morning, because they didn’t have anything like an ID or cell phone to help make a positive identification.

Pam Hupp returned to her home on Little brave Drive in O’Fallon at 11am Wednesday. Hupp and her husband had no comment after returning from Police Headquarters. Investigators say she cooperated with their investigation.

Police say she called 911 to report someone burglarizing her home at about 12:10pm Tuesday. She then reportedly called 911 again to say she shot and killed him.

Hupp was a key witness in the Betsy Faria murder trial. Betsy’s husband was convicted, then exonerated, after new evidence surfaced involving $150,000 in life insurance proceeds in which Pam Hupp benefitted. Hupp was never named as a suspect in that case and police say they’re continuing to investigate this shooting.

“The report from the victim was that he followed her into the house, and then she fired uh a round of shots, and he collapsed there,” said O’Fallon’s Chief Roy Joachimstaler.

Gumpenberger was from Union, MO. He has recent listed addresses, all over the place, including Bel Ridge, St. Charles and two locations in O’Fallon, Missouri.
