Rapper Tommie Walker a/k/a “Columbia BT” charged with trafficking cocaine

ATLANTA - Tommie L. Walker, a/k/a Columbia BT, and Juan Carlos Garcia-Martinez, a/k/a Carlos Garcia were arraigned before U.S. Magistrate Judge Linda T. Walker on September 21, 2018 on federal charges of drug trafficking and possession with intent to distribute cocaine.  Walker, Garcia-Martinez, and Samuel Anchondo-Galaviz were indicted by a federal grand jury on September 12, 2018.

“These defendants were allegedly part of a multi-state drug distribution scheme that transported and distributed cocaine worth approximately $4 million,” said U.S. Attorney Byung J. “BJay” Pak. “Thanks to the work of law enforcement in Georgia, South Carolina and Colorado, this drug enterprise is now history.”

“This investigation is an excellent example of the working relationships that the Drug Enforcement Administration (DEA) and the Atlanta-Carolinas High Intensity Drug Trafficking Area (HIDTA) have with their law enforcement partners,” said Robert J. Murphy, Special Agent in Charge of the Atlanta DEA Field Division. “The defendants were transporting large quantities of drugs throughout our neighborhoods, and the dismantlement of this criminal organization will have a positive local impact and sends a clear message that we will not tolerate illegal drug trafficking in our communities.”

According to U.S. Attorney Pak, the charges, and other information presented in court: Agents of the Atlanta-Carolina High Intensity Drug Trafficking Area program began their investigation in August 2017 in conjunction with Drug Enforcement Administration agents in South Carolina and Colorado. Walker, who raps under the name “Columbia BT,” allegedly participated in a cocaine trafficking conspiracy that extended to Colorado, South Carolina, and Mexico.

Walker allegedly operated a warehouse in the Atlanta area where he received shipments of cocaine hidden in tractor-trailers. The shipments were sent by a co-conspirator in Colorado. Walker allegedly would then distribute the drugs to individuals from South Georgia and South Carolina. Garcia-Martinez is an alleged co-conspirator who facilitated some of Walker’s drug transactions.

Law enforcement officers seized more than 135 kilograms of cocaine from the organization, a quantity worth more than $4 million at current wholesale prices in Atlanta. Law enforcement also seized more than $220,000 in drug proceeds.

October 9, 2017, a tractor-trailer containing approximately 40 kilograms of cocaine, which was driven by Anchondo-Galaviz, was stopped on the way to Walker’s warehouse. Other seizures charged in the indictment took place on December 3, 2017 and February 21, 2018.  Walker allegedly used his illegal drug proceeds to finance a lavish lifestyle that he displayed in his rap videos. Some of the property seized from the alleged drug proceeds included a 2016 Rolls-Royce Dawn and a 2013 Bentley Mulsanne.

Tommie L. Walker, a/k/a Columbia BT, 42, of Kennesaw, Georgia is charged with conspiracy to possess with intent to distribute cocaine and three counts of possession with intent to distribute cocaine.

Juan Carlos Garcia-Martinez, a/k/a Carlos Garcia, 37, of Forest Park, Georgia, and Samuel Anchondo-Galaviz, 40, of New Mexico are each charged with conspiracy to possess with intent to distribute cocaine and one count of possession with intent to distribute cocaine. Members of the public are reminded that the indictment only contains charges.  The defendant is presumed innocent of the charges and it will be the government’s burden to prove the defendant’s guilt beyond a reasonable doubt at trial.

This case is being investigated by the Drug Enforcement Administration, the Atlanta-Carolina High Intensity Drug Trafficking Area, the Bureau of Alcohol, Tobacco, Firearms, and Explosives, the Georgia State Patrol, the Clayton County Sheriff’s Office, the Marietta Police Department, and the Colorado Attorney General’s Office.

Special Assistant U.S. Attorneys Nicholas N. Joy and Erin Harris and Assistant U.S. Attorney Michael Brown are prosecuting the case.
