Convicted Serial Killer Exploited FBI Informant Status to Commit Multiple Murders Across Western U.S.: Report

Scott Kimball, 58, received a 70-year federal prison sentence in 2009 for four confirmed killings between 2003 and 2004, though former FBI Special Agent Jonny Grusing has suggested the actual number of victims could be significantly higher.

During this period, Kimball exploited his informant status to mislead authorities and hide his crimes, leaving investigators with lingering questions about his full scope of violence.

Before his time as an informant, Kimball had a long criminal history, including repeated fraud and stints in prison during the 1990s.
