Angel Monge-Mathuzima, who was convicted of second-degree reckless homicide during his trial in April, fatally stabbed 33-year-old Ryan Sorensen on Sept. 15, 2019, in the Milwaukee suburb of West Allis.

The stabbing was the result of a “physical altercation” between two groups southwest of Miller Park, West Allis police said.

A man and a woman approached Sorenson and friends early in the morning, and an argument ensued, police said. Sorenson was stabbed and died a short time later.

The man, identified later as Monge-Mathuzima, and the woman, subsequently identified as Shirley Louise Monge, fled before police arrived but were apprehended several months later.

Milwaukee County Circuit Court Judge Jefferey Wagner sentenced Monge-Mathuzima to nine years of extended supervision after his prison term.

Monge pleaded guilty to felony murder-battery as a party to the crime in May 2021, according to court records. Her sentencing, which had been scheduled for Tuesday, was delayed until July 11.
