Luke Barkhaus, 33, has been sentenced to 40 years in prison for a January 2025 spree of random violence that left three victims injured across Parker, Colorado—including a 7-year-old boy who authorities say was stabbed while searching for a Push Pop candy at Walmart.
Background
The attacks occurred on the same day in January 2025, according to the 23rd Judicial District Attorney's Office. Barkhaus first struck a restaurant employee before moving on to attack another victim inside a store approximately an hour later. His final and most shocking assault came when he entered a Walmart and singled out the young boy who was shopping with his mother.
According to an arrest affidavit, the child's mother told police she had been browsing the store for roughly 30 minutes before heading toward the westside checkout area. She allowed her children to pick out candy nearby—a routine errand that turned violent in an instant.
"Out of nowhere [the 7-year-old victim] told her, 'This man just punched me,' referring to an unidentified male suspect that was running away from them," the affidavit states. The mother reported her son "started bleeding from the side of his head" and immediately screamed for help.
Police later determined Barkhaus had sneaked up behind the boy without warning. In subsequent interviews, the child recounted hearing footsteps approach him as he stood selecting candy. He was looking for a Push Pop when the attack occurred.
"There is no fixing someone like this," District Attorney George Brauchler said in a statement Monday. "There is only protecting our community from him. This is why we build prisons."
The Sentencing
Barkhaus pleaded guilty to felony child abuse and two counts of first-degree assault before receiving his 40-year sentence this week, according to court records from the 23rd Judicial District.
Prosecutors presented damning evidence of Barkhaus's motivations during a January 2025 court hearing. When asked why he targeted innocent victims including the young boy, Barkhaus reportedly said "For the rush."
He also claimed in police interviews that he "would have continued to do it" to others had law enforcement not apprehended him, according to KMGH reporting.
"This malevolent menace said that he stabbed those innocent victims because he wanted to see what it was like to do it," Brauchler stated. "There is no fixing someone like this."
Prosecutors noted Barkhaus carries an extensive criminal history and has struggled with substance abuse and mental health challenges. According to Brauchler, Barkhaus "blamed his actions on years of huffing"—a reference to inhaling chemical vapors.
All three victims ultimately recovered from their injuries.
