A DEA agent accused of killing a cyclist in Salem while on duty had his case presented before a federal appeals court today in Seattle. At the center of today’s hearing was whether the agent could claim immunity from state prosecution because he was an on-duty federal agent. On March 28, 2023, Marganne Allen was riding her bike home from work in southeast Salem. Video from that day shows a black pickup truck running a stop sign moments before striking and killing the cyclist.
