Smith is considered by the DEA to be one of the largest cocaine and heroin dealers in Baltimore in recent years. U.S. Attorney Rod Rosenstein says his agency can prove Smith brought in more than 1,000 kilograms of cocaine into the city through an extensive operation that had drugs and money crisscrossing the country, often via car carrier.
The operation funded Smith's lavish lifestyle, which included pricey homes in Maryland and California as well as high-end cars, designer clothes and shoes and more.
ABC2 Investigators will take an in-depth look at the high life Smith was living as well as the case that brought him down Friday at 11 p.m. We sit down with the DEA special agent in charge of the case for an interview you'll only see on ABC2.
Although Smith apologized during sentencing, claiming he's not the monster prosecutors made him out to be, he still received a sentence at the higher end of the guidelines for his crime.
"I'm a work in progress," Smith told the court.
But he will now spend the next two decades attempting to change his ways. Smith will serve his time at a federal facility in New Jersey, his prison cell a far cry from the luxuries he acquired during his drug operation. Those assets, including $1.6 million in jewelry, more than $1 million worth in vehicles and $740,000 in cash has all been seized by federal agents
Smith's operation was ultimately broken up by an investigation that started with the traffic stop of a car carrier that turned up $2.3 million in cash in Arkansas in 2011. DEA agents used that tip to start their case against Smith, ultimately arresting him in Baltimore after gathering information over the course of two years.
