On the afternoon of March 20, 2016, 23-year-old Christian Ortiz was shot in Chicago’s Albany Park neighborhood and later died at Advocate Illinois Masonic Medical Center. The shooting occurred about 2:45 p.m. in the 4800 block of North Albany Avenue; Ortiz suffered a gunshot wound to the abdomen and was pronounced dead at 3:21 p.m. A 26-year-old man was also shot in the torso and hospitalized in critical condition.

Witnesses described a male suspect wearing a baseball cap and dark jacket who approached, opened fire, and fled on a bicycle. Ortiz lived in the 2400 block of West Bryn Mawr Avenue at the time. The Cook County Medical Examiner’s Office confirmed his identity and cause of death. No arrests were reported and the motive was not immediately clear; the case remains unsolved.

Does anyone who was in Albany Park that afternoon have information that could help investigators?
