Kauko Aho, 42, was fatally attacked on July 15, 2003, in San Diego. He was found collapsed in the front lobby of his apartment building at 3535 Monroe Avenue with his bicycle nearby. Aho had a deep stab wound to the chest and a slashing wound to his right arm and was bleeding heavily when a resident discovered him. He was taken to hospital and remained unconscious for about a week before dying of his injuries.

Investigators believe Aho had been riding his bicycle earlier that evening and was stabbed by unknown assailants somewhere near 4500 35th Street. He apparently managed to ride back to his building before collapsing in the lobby. The San Diego Police Department’s Cold Case Team and Crime Stoppers are seeking tips; the case remains unsolved.

If anyone has information about Aho’s route that evening, witnesses near 4500 35th Street, or other relevant details, please contact the San Diego homicide unit or submit an anonymous tip.
