Tyler Worthington, 34, of North San Juan, California, was found dead in a wooded area near Tuscumbia, Missouri, on June 11, 2018. An autopsy showed a single gunshot wound to the head, and authorities opened a homicide investigation.

Investigators connected Worthington to a large marijuana oil business. Searches of his California residence reportedly turned up hundreds of marijuana plants and more than 500 pounds of processed marijuana. Toll road cameras showed Worthington and Joseph P. McKenna leaving Chicago in separate vehicles on June 4, 2018; cameras recorded McKenna returning alone about 16 hours later. A financial dispute over the business was reported as a possible motive, and an associate told investigators McKenna had expressed intent to kill Worthington over a debt.

Joseph McKenna was arrested in September 2018 and charged with second-degree murder; a second man, Tyler M. Kroll of Lisle, Illinois, was later implicated and charged in connection with the trip to Missouri. What information can anyone offer about Worthington’s business ties or movements in early June 2018?
