One of two convicted in the September 2019 stabbing death of Ryan Sorensen in West Allis was sentenced to 16 years in prison on Monday, June 6.

One of two convicted in the September 2019 stabbing death of Ryan Sorensen in West Allis was sentenced to 16 years in prison and nine years of extended supervision on Monday, June 6.

Angel Monge Mathuzima and Shirley Monge, husband and wife, were convicted in the case. Monge Mathuzima was found guilty by a jury on one count of second-degree reckless homicide, use of a dangerous weapon, as party to a crime. Monge in May 2021 pleaded guilty to one count of felony murder – battery, as party to a crime. Monge was supposed to be sentenced Monday as well, but she could not appear in court because her attorney tested positive for COVID-19. Her sentencing was pushed back to July.  

Just before 2 a.m. on Sept. 15, 2019, Sorensen and two friends were walking near71st and Beecher when the married couple rode past on their bikes. Sorensen allegedly made a comment about wanting their bikes and that upset the woman, according to the criminal complaint.

Monge allegedly circled back around Sorensen and "angrily spoke" to the group, the complaint said.

According to a member of the group, Monge got close to Sorensen and was either pushed off her bike or she ran into him and fell off. Sorensen allegedly knocked Monge's phone out of her hand, and that is when she started swinging at the victim. The husband also joined in on the fight, the complaint said.

An investigation found blood in the street matched that of Monge Mathuzima, according to the Combined DNA Index System. Billing records also showed he lived two blocks from where the incident occurred. 

Monge was questioned by police, and she admitted to being involved in the incident, saying an argument happened, she was pushed off her bike and Sorensen put her in a chokehold. She said that's when her husband intervened, according to the complaint. 

Again, Mathuzima was sentenced to serve 16 years in prison.

"I would’ve liked to see him go away for life, but it is what it is," said William Sorensen, Ryan's father.

In this final chapter of an almost three-year horror story, Sorensen’s family is grieving his tragic death all over again.

"The nightmare that I’ve been living for the past three years does not end with this," said Terese Dineen Sorensen, Ryan's mother.

Before the sentence was handed down, Monge Mathuzima expressed remorse.

"I would like to apologize for my actions that led us to be here today," said Monge Mathuzima. "I’d like to apologize to Ryan's family for their loss, and that I had no intention of killing anyone that night." 

"The person that I know is a kind-hearted, loving father, friend and brother," said Oscar Garcia, friend of Monge Mathuzima. 

Monge Mathuzima's loved ones were also in court for the sentencing hearing, and tears fell from both sides as the sentence was read.

"All my son had and all he aspired to be was taken away from him by this senseless, cruel act of murder," said William Sorensen. 

"I am sorry for your family, your kids and your mother, but I am not sorry for you," said Terese Dineen Sorensen. 

"They talk about closure, and I would say that to people but there will never be closure," said William Sorensen. . "His birthdays, the holidays, his 12:01 birthday calls, April Fools' jokes, St. Patrick's Day, all of those are gone forever."
