The U.S. Attorney's Office announced the indictment of seven Baltimore men, including one for the 2014 murder of 3-year-old McKenzie Elliott.
Authorities said Terrell Plummer fired the shots that killed McKenzie during a "turf battle" in Waverly back in the summer of 2014. Plummer's stray bullet hit McKenzie while she was playing on her front porch.
The alleged gang members were part of the "Old York Money Gang" in Waverly, according to authorities.
This will be the last presser announced by U.S. Attorney General Rod Rosenstein before he takes office as the nation's deputy attorney general.
McKenzie Elliott would be six years old. Police Commissioner Kevin Davis said during a press conference that the city never forgot about this case.
"To be able to close cases like this is good for the city, but we need to get the murder rate down," Mayor Catherine Pugh said after the indictments were announced.
"We need the message to get out there that if you're part of a gang that's involved in shootings, we're going to be coming after your entire gang. That's a strategy that I hope will be seen throughout the country," Rosenstein said.
The indictment claims Plummer and six other men -- Davonte Rich, Trevon Beasley, Tyrone Jamison, Davin Lawson, Calvin Watson, and Tyron Brown -- are part of OYMG.
For years they trafficked drugs, stole, and robbed several people in the area defending their 'turf' and threatening anyone who posed as a threat.
Now each of them face drug trafficking charges.
"These are violent repeat offenders -- the list of names in front of you. So, the list of names in front of you, they're not strangers to the Baltimoe Police Department. They're no strangers to our federal partners," Davis said.
Federal agents with ATF's Baltimore division say the group has been on investigators' radar since January of 2014.
"It's even worse because there are innocent people that are affected by this violence," Rosenstein said.
Innocent people like McKenzie, who's murder went unsolved for three years, and Rosenstein says could've been a lot sooner.
"If we encourage those officers, if we support those police officers that are out there working for the community every day, we're going to be able to turn the tide on violence in Baltimore city," he said.
Plummer could face the death penalty or life in prison.
