DETROIT, MI – A Michigan man pleaded guilty Friday to a federal conspiracy charge for running a drug-trafficking ring that used couriers to hide heroin and cocaine in luggage on flights from Los Angeles to Detroit.

Kevin “Wood” Blair, 46, is set to be sentenced Dec. 17 on the charge of conspiracy to possess with intent to distribute heroin and cocaine, which carries a mandatory minimum penalty of 10 years in federal prison, according to the U.S. Attorney’s Office.

Assistant U.S. Attorney Alex Wyman told the court that Blair was the “organizer or leader” of the scheme, which involved four defendants and began on an unknown date and lasted until law enforcement moved in last year.

Two co-defendants in the case — Kennsha Mason and Delano “Bop Bop” Leflore — previously pleaded guilty and are awaiting sentencing. The third, Gabriela Maria De Leon, also pleaded to the conspiracy charge and was sentenced Wednesday to time already served for her lesser role in the scheme.

The case began to unfold in March 2017 when authorities discovered more than four pounds of heroin and two pounds of cocaine in checked luggage at Los Angeles International Airport. The luggage belonged to Mason, 30, of Detroit, who acted as a courier.

Leflore, 38, also of Detroit, had hired Mason to transport the drugs and made arrangements for her to travel to Los Angeles. Upon arrival, Mason went to a townhouse on South Oakland Avenue in Pasadena, where Blair supplied the narcotics that were discovered by law enforcement in her suitcase, according to federal prosecutors.
