Domestic Violence Double Homicide Defendant Sentenced

DENVER—In September 2021, Katherine “Katy” Pivoda and her friend Jennifer Gelvin were found stabbed to death in the backyard of Pivoda’s Denver home by Denver Police Department officers. Officers also contacted Pivoda’s former husband, Matthew Madden (current age 38), who was in the house covered in blood and holding a knife. Prosecutors with the Denver District Attorney’s Office filed charges against Madden.

“This senseless act of violence affected not one but two families and the community as a whole,” said Chief Deputy District Attorney Effie Antonopoulos. “We believe that Jennifer was trying to help Katy when she was murdered by Matthew Madden.”

In April 2023, Madden pleaded guilty to two counts of second degree homicide. Today, the Honorable Judge Nikea Bland sentenced Madden to serve an 80-year term (40 years for each victim) in the Colorado Department of Corrections. This is Denver District Court case number is 21CR005842.
