George M. Montoya was a Special Agent with the DEA who was killed on February 5, 1988, in Pasadena, California. He and colleague Special Agent Paul Seema were conducting an undercover buy of $90,000 worth of heroin when they were ambushed on the 1400 block of South Marengo Avenue. Seema was shot in the head by one suspect; Montoya was shot in the head by another who arrived in a separate vehicle. A third agent returned fire as the suspects fled.

The fleeing suspects were pursued; a high-speed chase ended in a shootout on Monterey Road in San Marino. Two suspects, identified in reports as William Wei Wang and Frank Kow, were killed in that confrontation; another suspect was arrested. Additional suspects who had fled in a separate vehicle were also taken into custody. Prosecutors later charged planners and accomplices, including Michael Chia, who was convicted of murder for planning and aiding the robbery that led to the agents’ deaths.

Does anyone have additional details about the ambush location or witnesses to the initial exchange on South Marengo Avenue?
