A federal agent shot and killed while questioning a passenger on an Amtrak train in Arizona is being remembered as a venerated leader and mentor with an unparalleled work ethic.
Dozens of family, friends and colleagues filled Calvary Chapel in Tucson on Friday to honor Michael Garbo, a longtime Drug Enforcement Administration group supervisor.
He was part of a regional task force of DEA agents and local police inspecting baggage Monday at the train station downtown when the shooting erupted.
Another agent and a Tucson police officer were also wounded.
Officials credit Garbo's leadership with saving the lives of other passengers and his colleagues.
The shooter was killed by officers' gunfire.
