DENVER — A man charged with fatally stabbing his estranged wife and her friend pleaded guilty Friday to two counts of second-degree murder.
Matthew Madden, now 38, killed 33-year-old Katherine Pivoda and 49-year-old Jennifer Gelvin in September 2021.
Officers said they found two women with stab wounds when they responded to the 2200 block of South Marion Street for a domestic violence incident on the night of the crimes. Both were pronounced dead at the scene.
Pivoda was Madden's estranged wife, and Gelvin was her friend.
Two sleeping children were also found in the home. They were not hurt.
According to a probable cause statement, Madden was bloody and holding a knife when they found him. They tased him after he refused to drop the knife, and the document says he was taken to the hospital in critical condition for treatment of self-inflicted injuries suffered before his arrest including cuts on his neck, chest and arms.
The PC statement says neighbors reported hearing an argument from their homes and someone yelling "get out" repeatedly before the commotion stopped.
A witness also told police that Madden had moved out around July of that year.
Sentencing is set for June 30.
