He shot and killed his girlfriend’s mom last year. Now Wichita man is going to prison

A 30-year-old man has been ordered to serve 44 years in prison for killing his girlfriend’s mother and injuring another woman in a shooting in southeast Wichita last year.

“District Judge Sean Hatfield this afternoon followed the plea agreement and sentenced Matthew Alexander III, 30, of Wichita, to 528 months in prison with 36 months post release,” Dan Dillon, a spokesman for the Sedgwick County District Attorney’s Office, said Friday by email.

The judge also ordered $3,748 in restitution be paid to the Kansas Crime Victims Compensation Fund and the prison term “run consecutive to the remainder of a federal sentence Alexander received for his conviction of possession of a weapon by a prohibited person,” Dillon said.

Alexander pleaded guilty on May 10 to amended counts of second-degree reckless murder and attempted second-degree murder in the shootings of 48-year-old Addriane Kenney and her 22-year-old daughter, as well as one count of aggravated burglary, court records show. Kenney, who had been shot in the head, died at the scene from her injuries. The daughter survived and called 911, court records say.

Police and prosecutors have also spelled Kenney’s first name as “Adraine.”

Wichita police responded to the shooting at 831 S. Mission, near Lincoln and Woodlawn, around 11:25 p.m. on Sept. 21, 2023. Police have said previously that the shooting was “domestic related” and that Alexander and the victims had lived together. Court records say Kenney was his girlfriend’s mom.

Court records also say Alexander showed up at the address the night of the shooting wearing a light-colored ski mask, told everyone there “It’s demon time” and “you better leave before I pop you” then pulled a gun from his hoodie and started shooting. He shot the 22-year-old woman first. When she ran, he fired two more times, according to court records.

Then he “ran up behind ... (Kenney) and fired one time” at the back of her head, court records say.

In the days before the shooting, Alexander had gotten “irate,” threw property around, stole a car and fired a gun after having a conversation with his girlfriend about bringing his new baby to their house, court records say. Before the shooting, he was also involved in a verbal argument with his girlfriend about her contact with other people and was upset about a drink that hadn’t been put in the refrigerator, according to an affidavit released by the court.

Officers arrested Alexander in the 600 block of South Mission after a brief standoff that ended when he surrendered peacefully, police have said.
