Thornton police spent early Friday morning combing through a fitness-center parking lot near 104th Avenue and Washington Street after a reported stabbing that pulled officers to the busy intersection before sunrise. Investigators stayed on scene into the morning, blocking off part of the lot as they tried to piece together exactly what unfolded.

What Police Said

According to CBS News Colorado, officers were dispatched early Friday on a report of a stabbing in the fitness-center parking lot near 104th and Washington. The outlet aired a brief clip showing marked units and crime-scene tape at the location but offered few additional specifics while the investigation was still in full swing.

How To Help

The Thornton Police Department is asking anyone who might have seen something or captured cellphone or dashcam footage to contact its tip line at 720-977-5069, according to the department's newsroom. Officials stressed that even small details or partial video can help detectives connect the dots and urged anyone with relevant information to reach out.

Local Context

The call comes just weeks after Thornton officers arrested a suspect in a March 25 fatal stabbing, a case the Denver Gazette reported on April 3. That killing, along with other recent violent incidents, has kept the city’s detectives busy this spring and added to community concern about serious crime.

Authorities have not released information about the victim’s condition or given any description of a possible suspect, and they say the investigation remains active. Police are again urging anyone with tips about the incident near 104th and Washington to call the Thornton Police Department tip line at 720-977-5069 as they continue their work at the scene and behind the scenes.
