Luke Barkhaus pleaded guilty to felony child abuse and two assault counts tied to three January 2025 attacks in Parker and Aurora.
CASTLE ROCK, Colo. — A Colorado man who attacked three strangers, including a 7-year-old boy inside a Walmart, has been sentenced to 40 years in prison after pleading guilty to felony child abuse and two counts of first-degree assault.
Luke Barkhaus, 33, was sentenced after a series of attacks on Jan. 26, 2025, in Parker and Aurora, according to the Parker Police Department and the 23rd Judicial District. Police described the violence as unprovoked and said the victims included a restaurant employee, a child shopping at Walmart and a woman attacked inside another store. Barkhaus was arrested in Aurora two days later.
The sentence resolves the main criminal case more than a year and a half after the attacks. Barkhaus had previously pleaded not guilty to eight felony charges, including assault, attempted assault, menacing and child abuse. A trial had been scheduled for April 2026, but the case was later resolved through guilty pleas to felony child abuse and two first-degree assault counts.
Police said the first reported attack involved an employee at a restaurant. About an hour later, another attack was reported at a business, and authorities later connected Barkhaus to the stabbing of the 7-year-old at Walmart. The most recent Parker police account lists the restaurant attack first, followed by the Walmart attack and another store attack. Earlier reports did not establish the exact order of all three incidents, and authorities have provided differing sequences over the course of the case.
The child was shopping with family members when he was attacked without warning, according to investigators and earlier court reporting. Authorities said he suffered an injury to his head and was expected to recover. Officials have not publicly identified the boy. One of the adult victims was also taken to a hospital with injuries that were not considered life-threatening.
Investigators identified Barkhaus through surveillance footage gathered after the attacks. Parker detectives said video showed a suspect leaving one of the locations and getting into a vehicle. Police were able to obtain the vehicle’s license plate information and worked with the Douglas County Sheriff’s Office to locate Barkhaus in Aurora. He was arrested Jan. 28 and taken into custody.
Barkhaus initially had a bond of $100,000, which was later increased to $1 million as the criminal case moved forward. Prosecutors said statements attributed to Barkhaus after his arrest showed that the victims had been selected at random. At an earlier court hearing, prosecutors said he described carrying out the attacks “for the rush.” District Attorney George Brauchler later said Barkhaus told authorities he wanted to know what committing such an attack was like.
Parker Police Chief Jim Tsurapas credited investigators and other law enforcement officers who worked to identify and arrest Barkhaus. “These senseless and unprovoked attacks placed innocent people, including a child, in grave danger,” Tsurapas said after the sentence was announced. He said the prison term prevents Barkhaus from posing a further threat to the community.
Senior Deputy District Attorney Lauren Raible said the attacks had lasting effects on the victims, particularly the child and his family. She said prosecutors hoped the lengthy prison term would give the victims time to recover while Barkhaus addresses issues connected to his criminal behavior. Police also said Barkhaus had an extensive criminal history before the January 2025 attacks.
Barkhaus is now set to serve the 40-year sentence in the Colorado Department of Corrections. Authorities have continued to protect the identities of the victims, and the sentencing marks the latest confirmed development in the criminal case stemming from the three attacks.
