How Not to Get Away with Murder

Jonathan Mosher

Chief Trial Counsel

Pima County, Arizona Attorney’s office

As Chief Trial Counsel, Jonathan prosecutes homicides, cold cases, violent felonies, sexual assaults, and crimes against children in Tucson, Arizona. He lectures at training seminars for prosecutors throughout Arizona and nationally. He has been recognized by the Arizona Prosecuting Attorneys Advisory Council (APAAC) for Excellence in Victim Advocacy (2009) and as Felony Prosecutor of the Year (2011). He has also received the Association of Government Attorneys in Capital Litigation (AGACL) Board of Directors Advocacy Award (2017) (for his prosecution of State v. Watson, a case featured on Dateline NBC’s “Secrets of the Desert” episode).

After graduating from Colgate University (1991) and the University of Iowa College of Law (1994), Jonathan served as a law clerk with the Arizona Supreme Court. He then spent nearly a decade in private practice specializing in environmental litigation with the Los Angeles offices of two international law firms; Gibson, Dunn & Crutcher and Latham & Watkins. In 2003, he wrote “A Pound of Cause for a Penny of Proof: The Failed Economy of an Eroded Causation Standard in Toxic Tort Cases,” published in the NYU Environmental Law Journal. In his free time, to scare criminal cases out of his mind, he climbs rocks.
