CASE DETAILS

Just a few hours after heavily insured millionaire rancher E.C. Mullendore III was found shot in the head, Gary Glanz was called in to provide security for the murdered man’s estranged wife and family amid rumors that it was a mob hit.

Within hours of the murder, Glanz would find himself at the crime scene, the sprawling Cross Bell Ranch in northern Oklahoma, where he established contacts with law enforcement officials and ranch employees. Over time, his role would evolve into a full-scale investigation of the murder, taking him from Kansas City to Atlanta to Seattle to the Bahamas as he tracked down leads.

Eventually, the case would come to be regarded as the biggest unsolved murder in Oklahoma history, attracting the attention of The Wall Street Journal and becoming the subject of a Warner Bros. book. Glanz’s work would lead to an $8 million insurance settlement for the dead man’s family, reportedly the largest in the history of the U.S. underwriting industry, according to Guinness World Records.
