On July 10, 2007, 46-year-old Eusebio Barboza-Agular stepped out of his Denver home on the 4300 block of Fillmore Street with his son to go to work. An unknown male approached them, a brief verbal exchange occurred, and the man then produced a gun and fired multiple times at close range, striking Eusebio while his son stood nearby. Eusebio was transported to hospital but died of his wounds.

The suspect has been described only as an unknown male; no detailed description of his appearance, clothing, vehicle, or direction of flight has been released, and authorities have not publicly identified a motive. The Denver Police Department classified the incident as a homicide and the case is listed in the Colorado Cold Case Files as unsolved. The Denver Police Cold Case Unit continues to seek tips and encourages anyone with information to contact Denver Police or Crime Stoppers.

If anyone knew Eusebio, was present that morning, or has information about who confronted him, please share what you know with investigators.
