ST. LOUIS -- Tyrone Williams and Harold Williams, both of Hannibal, Mo., were two of three men sentenced to prison Wednesday for their roles in a conspiracy to traffic narcotics in Northeast Missouri and West-Central Illinois.
Tyrone Williams, 37, was sentenced to 10 years and one month by U.S. District Judge Audrey G. Fleissig.
Harold Williams, 30, was sentenced to nine years and four months.
A third man, Terry T. Williams, 34, of St. Louis, was sentenced to five years.
Court documents say that between 2004 and 2016, the three men all assisted in bringing large amounts of cocaine and cocaine base into Northeast Missouri and West-Central Illinois for distribution.
Tyrone Williams and Justin Woodson of St. Louis, who was previously sentenced to a term of 10 years, maintained out-of-state sources of cocaine and would take the drug back to Hannibal for sale.
Both Terry Williams and Harold Williams acted as street-level distributors on behalf of Tyrone Williams and Woodson.
As part of his plea agreement, Tyrone Williams also admitted to having told Harold Williams to assault a cooperating witness in the investigation.
U.S. attorney Jeff Jensen said, "We are grateful for the collective hard work of Hannibal area law enforcement officials."
The case was investigated by multiple law enforcement agencies, including the Drug Enforcement Administration, the West Central Illinois Drug Task Force, Quincy Police Department, Troy (Mo.) Police Department, Lincoln County (Mo.) Sheriff's Department, Adams County Sheriff's Department, Hannibal Police Department and the Northeast Missouri Narcotics Task Force.
Assistant U.S. Attorney Angie Danis handled the case for the U.S. Attorney's Office.
