Joseph P. McKenna is being held in Chicago, pending his return to Missouri. McKenna is charged with the murder of Tyler Joseph Worthington.

As a Chicago man awaits extradition to Missouri to face murder charges, a case put together with the help of multiple law enforcement agencies points to a drug deal that went bad on a rural road in Miller County.  

Joseph P. McKenna is being held in Chicago, pending his return to Missouri. McKenna is charged with the murder of Tyler Joseph Worthington.

Court documents filed in Miller County by investigators in the case indicate a well established and successful pot  operation and distribution system were being operated by Worthington. His body was found in a wooded area off Dry Creek Road near Tuscumbia in June. Investigators now believe he was murdered by McKenna, a known business associate involved in the sale of pot oil.  

On June 11, 2018, unidentified human remains were located in a wooded area, just off a rural Miller County road, near Tuscumbia. Evidence at the scene indicates the victim was shot at that location and dragged into the woods, from the roadway. 

On June 13, 2018 an autopsy determined the cause of death to be a single gunshot wound to the head and fingerprints confirmed the body was that of  Worthington, 34, of North San Juan, California.

Investigators discovered that Worthington owned and maintained a large marijuana grow operation in and around his home in North San Juan, California. He was engaged in the growing of marijuana as well as heavily involved in the production of marijuana oil. Investigator's also learned from an interview with a close associate of Worthington's that he supplied this marijuana oil to McKenna, 36, of Chicago, Illinois. 

Investigators found that after Worthington extracted the marijuana oil, it was shipped to McKenna, who then loaded the marijuana oil into cartridges for use in vapor style smoking devices. 

During the execution of a search warrant at the home of Worthington, invoices were found showing a large number of new, empty vapor pen cartridges, along with specialized equipment to fill those cartridges were purchased by and shipped to McKenna Services, Inc., 2701 W. Fulton Street, Apartment #5 S, Chicago, Illinois. 

Also found during the search warrant was over 500 lbs of processed marijuana, green houses containing hundreds of marijuana plants, growing and cultivating supplies, and processing equipment including specialized equipment used in the extraction of marijuana oil. Other documents found during the execution of the search warrant included a handwritten ledger, which recorded details about the extraction of marijuana oil from plant material. 

An interview with Worthington's fiancee' indicated  that on June 2, 2018, Worthington flew to Chicago, Illinois to meet with  McKenna, who she described as an individual active in the dealing of drugs and one who Worthington "works with". She alleged that during his trip to Chicago, Worthington along with McKenna were planning to drive from Chicago, Illinois to Missouri to "do a job". 

Investigators confirmed that Worthington flew out of Sacramento airport on June 2,  to Chicago O'Hare Airport. Upon arrival, Worthington rented a white 2018 Toyota Corolla (Still missing) from Hertz Rental Car. Worthington was reported to have driven separately in his rental car, from McKenna, but traveled with him during the trip to Missouri. Toll road records show that  McKenna's 2009 Chrevrolet truck and Worthington's rental car passed through the Cermak and Joliet tolls together, headed out of Chicago, just seconds apart on June 4, 2018. It was also discovered later that same day,  McKenna's truck went through northbound tolls, on its way back into Chicago, without Worthington's rental car. The approximate drive time from Chicago to the location where Worthington was murdered is 14 hours, round-trip. From the time McKenna left Chicago till the time he returned was 16 hours and 17 minutes.

During interviews with a close associate of Worthington's, he said the two were  engaged in the production and sale of marijuana oil loaded vapor pen cartridges. While conducting a phone interview with the associate, he received a phone call from McKenna, on another line. He placed the other line on speaker phone and an investigator was able to listen and record the conversation between the two. 

During the conversation, McKenna allegedly describes what investigator's and he believe is the likely drug deal he and Worthington conducted in Missouri and details of how he last saw  the victim leaving with a large sum of money from that transaction. 

McKenna reported that they "unloaded" product in two locations that day and after the last stop, Worthington was planning to purchase carbon paper, reportedly used to conceal large sums of money from law enforcement. McKenna indicated the plan was to deliver those packages of money to an individual back in Chenoa, Illinois. From there  it  was allegedly going to be loaded into a tractor trailer and shipped. 

McKenna stated he was supposed to fly back to Sacramento, with Worthington, on June 5. Investigators learned that McKenna and his girlfriend flew back, without Worthington, on that date. During a face to face interview with the associate  he was able to show investgators an actual marijuana vapor pen cartridge produced by Worthington and McKenna, that he had personally obtained and used.

Investigators believe there is probable cause to indicate that Worthington and  McKenna came to Missouri on June 4,  to commit the crime of delivery of a controlled substance, which is a class C felony. During the commission or attempted commission of the delivery,  Worthington was murdered.
