An 18-year-old accomplice in the brazen shooting at the Rockville Metro station in May of 2012 is heading to prison.
Police say Tavares Harris provided the gun that Kevin Nguyen used to shoot his rival four times and graze an innocent bystander.
"This is the settling of a small disagreement in a violent deadly fashion, in a public place that could have ended up with great loss of life," Deputy State's Attorney John Maloney says.
Jarrod Cannon survived the shooting. So did Wasima Gary, who was grazed by a bullet.
Nguyen pleaded guilty and is serving a 25-year sentence.
Harris has been sentenced to 20 years in prison – 15 years for first degree assault and five years for a weapons charge.
"He's the one who brought the gun to the Metro,” says Maloney. “He's the one that handed the gun to the shooter. He's the one that encouraged everything to occur.”
Prosecutors say the Metro shooting was gang-related -- a lifestyle Harris glorified in online videos.
Maloney says the judge who sentenced Harris is sending a strong message on two fronts: gang involvement and holding accomplices accountable in Montgomery County.
"I think the message has to be said. If you're part of a group that wanted to engage in this type of violent activity, whether you're the shooter or the person that just encourages it, you will end up in jail and you'll end up in jail for a very long time," Maloney says.
