CHEYENNE, WY – June 2, 2025 — A Cheyenne man is in custody after a violent stabbing left another man with life-threatening injuries in a residential neighborhood on Sunday evening.
The Cheyenne Police Department responded to a call for service at approximately 6:18 p.m. on June 1, 2025, in the 2400 block of Pattinson Avenue. Upon arrival, officers discovered an adult male victim suffering from multiple stab wounds. Emergency personnel immediately rendered aid at the scene before transporting the victim to Cheyenne Regional Medical Center, where he remains in critical condition.
According to police, the suspect, identified as 31-year-old Sterling Null, had already fled the scene before officers arrived. Witnesses informed police of Null’s identity and direction of travel, prompting a swift manhunt. Investigators say Null was later located and taken into custody without further incident.
Details of the attack reveal a deeply disturbing sequence of events. Authorities say that prior to the stabbing, Null was observed driving a Dodge passenger car at an excessive rate of speed. He entered a parking area on Pattinson Avenue, where he crashed into a vehicle belonging to a family member, causing a chain-reaction collision that pushed the impacted vehicle into the victim’s parked truck.
Witnesses reported that following the crash, Null exited his vehicle and attempted to flee. When the victim saw him and called out, asking for an explanation or attempting to intervene, Null turned around and allegedly charged at the unarmed victim in an aggressive and violent manner.
According to CPD, Null swung his arm back and repeatedly thrust a knife into the victim’s torso, inflicting several stab wounds before fleeing the scene on foot. Multiple residents in the area witnessed the altercation and provided statements to officers.
“This was an extremely violent and targeted attack that could have easily turned fatal,” said a CPD spokesperson. “Thanks to the quick response of residents and our officers, the suspect was apprehended before anyone else was harmed.”
Cheyenne Police say they believe the incident may have stemmed from a personal dispute, but the investigation remains active. Detectives are working to gather all relevant details, including the events leading up to the confrontation and any possible motives.
Sterling Null has been arrested and is currently being held at the Laramie County Detention Center. Formal charges are expected to be filed soon, which may include aggravated assault with a deadly weapon and other related offenses.
