SPRINGFIELD, Mo.—A major methamphetamine bust occurred in Springfield this year and most recently another co-conspirator was sentenced.

According to a press release from the office of the U.S. Attorney for the Western District of Missouri, 35-year-old Jami L. Deam, of Marshfield, was sentenced by a U.S. District Judge to nine years in federal prison without parole for her role in a drug-trafficking scheme that spanned nearly four years. Deam’s role involved transporting methamphetamine and heroin as well as selling the drugs. Mainly, she transported drugs from Texas, Arizona, California, and St. Louis, MO to the conspiracy leaders in Springfield. Conspiracy leader 46-year-old Christopher “Big Al” Jefferson, of Springfield, who was sentenced to 25 years in federal prison without parole, frequently had women, like Deam, transport drugs for him. Co-leader in the scheme, Donald “Dee” Taylor was also arrested and plead guilty but is awaiting sentencing.

Additional conspirators include , 32-year-old Davetta F. Hicks, of Springfield, who was sentenced to five years and 10 months in federal prison without parole and 48-year-old Shawn B. Robinson who received six years in federal prison without parole.

The case was investigated by the DEA, Springfield Police Department, and the Combined Ozarks Multi-jurisdictional Enforcement Team and is currently being prosecuted by Assistant U.S. Attorney Abram McGull II.
