A dispute in a Phoenix alleyway on the morning of October 7, 2017, left David Allen Setterberg critically wounded and ultimately dead. At about 9:40 a.m. he argued with an unidentified Hispanic man and woman behind 2520 E. Indian School Rd.; the male then shot Setterberg and fled with the woman, taking Setterberg’s yellow bicycle. Setterberg survived for about a month before dying from complications of the gunshot wound, at which point the investigation became a homicide inquiry.

Authorities described the male suspect as Hispanic, 20 to 30 years old, short build, wearing a Phoenix Suns jersey and riding a low-rider style bicycle. The female companion was also described as Hispanic. No arrests have been publicly announced and the Silent Witness program has offering a reward for information leading to an arrest. Details about Setterberg’s age and ethnicity were not provided.

Does anyone have information about that morning behind 2520 E. Indian School Rd. or recall seeing a man in a Suns jersey with a low-rider bike in the area?
