Investigators have classified the death of Louis Gumpenberger, 37, as a homicide. He was killed Tuesday inside Hupp’s O’Fallon home.
Hupp told police Gumpenberger confronted her outside her home and followed her inside.
Hupp was a former witness in the high profile Betsy Faria murder trial. Betsy’s husband, Russ, was first convicted and later exonerated after new evidence surfaced. The evidence involved $150,000 in life insurance proceeds, signed over into Hupp’s name days before Betsy’s murder.
Hupp was never named as a suspect during the Faria investigation and O’Fallon police are not talking much about this shooting because they’re still investigating.
