TIMELINE: DEA agent indicted 5 months after fatal cyclist collision

Over five months after a Salem cyclist was killed in a collision, an agent of the U.S. Drug Enforcement Administration has been charged in her death.

A Marion County grand jury on Wednesday indicted 38-year-old Samuel Landis, a DEA special agent, on a charge of criminally negligent homicide. He is accused of killing cyclist Marganne Allen, 53, with “criminal negligence,” according to the indictment.

Salem Reporter established the sequence of key events between March 28 fatal collision and the indictment of the DEA agent. The timeline is based on public records obtained from Salem and Keizer, legal submissions by the city of Salem, statements from the two police agencies to the news organization and public court documents.
