Gregory Hogan was 32 when he died of multiple gunshot wounds on December 16, 1990, in San Bernardino, California. He was found in a residential neighborhood described as having a high crime rate. Investigators treated the shooting as a targeted attack based on the wounds and circumstances at the scene.

The San Bernardino Police Department opened a lengthy investigation that initially questioned several suspects but remained unsolved for a long time due to scarce eyewitness accounts and limited physical evidence. Years later, new forensic techniques applied to the original evidence identified a suspect who had a history of violent crimes; that person was arrested, charged and ultimately convicted at trial after prosecution evidence and witness testimony were presented.

Reports from the proceedings raised allegations of evidence mishandling and procedural errors that had impeded the early investigation and prompted calls for reform. Does anyone have additional information about Gregory Hogan or his case that could help provide more context?
