"The original local organization retained its identity, leadership structure and operations, but its members publicly called themselves members of the BGF," prosecutors said in a statement. "New name, same violent business."

When King was shot and killed in 2007, prosecutors say, fellow gang member David Hunter vowed to avenge his death. They say he waited more than three years before exacting revenge on the man he believed responsible, gunning down Henry Mills in the 2400 block of Greenmount Ave.

Hunter became a leader of the organization following King's death, prosecutors said. A call to his public defender was not returned Thursday, nor was a message left with District Public Defender Elizabeth L. Julian.

Prosecutors accused the suspects in dozens of attacks over the past several years:

•In 2009, they said, David Hunter shot four people in the 400 block of E. Lanvale St., allegedly yelling "This is BGF territory" as he fired.

•They said alleged YGF leader Donatello Fenner, whom former Police Commissioner Frederick H. Bealefeld called a "catalyst for violence," was killed in March 2010 for violating gang code.

•They said a man was shot in April 2011 for allegedly talking to police

•On March 23, 2013, they said, a man named Moses Malone was robbed and shot in the 2400 block of Greenmount Ave. by alleged BGF member Norman Handy.

•About five weeks later, prosecutors said, Handy's brother, Wesley Brown, shot Malone to death, believing he was going to testify against Handy for the robbery and shooting.

•A man named Trevon White allegedly helped tip off Brown to Malone's whereabouts. Prosecutors say White was shot and killed on May 7 in the 200 block of E. 22nd St.

The public defender's office did not respond to requests to speak with representatives for suspects in the case.

The violence wasn't isolated to East Baltimore. In June, prosecutors said, BGF members converged on the Mirage night club for a birthday party for Brown and another alleged gang member, and a man was shot in the 300 block of W. Fayette St. following a disagreement.

Prosecutors hoped that Thursday's indictments would dismantle the BGF's power structure at least in East Baltimore, where several redevelopment projects are underway. Residents welcomed the operation, hoping it would clean out some of the stubborn violence that has been keeping investors away.

"We're all aware of drug activity in the community, and there have been people engaged in that for years," said W. Brad Schlegel, a spokesman for the Barclay-Midway and Old Goucher Coalition.

Barclay, a community that includes the city schools headquarters and is located just north of North Avenue near Green Mount Cemetery, has been the focus of recent revitalization efforts, with the entire 400 block of E. 20th St. razed to make way for new homes.

But it remains challenged by crime. There have been four homicides and three non-fatal shootings there this year alone.
