Alfredo Olivares Jr, a 19-year-old Hispanic male, was fatally shot on September 19, 2020, in Fort Worth, Texas. He was hanging out in the street on Valentine Street when the shooting occurred around 6 a.m.; Olivares was taken to John Peter Smith Hospital, where he died. At the scene police reported no known motive and initially no arrests had been made.

Discrepancies in the medical examiner’s work complicated the investigation. The autopsy report listed one projectile despite other records indicating two, and a Tarrant County judge approved exhumation to search for a possible second projectile. An audit later identified errors in more than two dozen homicide cases, including Olivares’s, and led to the suspension and termination of Deputy Medical Examiner Dr. Marc Krouse.

Reports state a suspect, Peter Cardona, 23, was arrested for murder. What information do readers have about the shooting that could help clarify the timeline or motive?
