A man who stabbed his estranged wife and her boyfriend to death in Denver has been sentenced to 80 years in prison.
Matthew Madden, 38, was convicted Friday of the September 2021 deaths of Katherine “Katy” Pivoda and Jennifer Gelvin, That’s according to the Denver District Attorney. Pivoda was estranged from Madden at the time. Both women died at the scene from multiple stab wounds.
The women were stabbed in the backyard of Pivoda’s home in the 2200 block of South Marion Street. Officers responding to the attack found Madden in the house covered in blood and holding a knife.
“This senseless act of violence affected not one but two families and the community as a whole,” said Effie Antonopoulos, deputy district attorney. “We believe Jennifer was trying to help Katy when she was killed by Matthew Madden.”
In April, Madden pleaded guilty to two counts of second-degree manslaughter, according to the district attorney’s office. On Friday, Denver District Judge Nikea Bland sentenced Madden to 40 years in prison for the death of each victim with consecutive terms.
