In East Boston, six teenagers dead since last fall

East Boston residents plan a peace vigil at 5 p.m. on Thursday in East Boston Memorial Stadium, near where the body of a teenager stabbed to death was found Christmas eve.

The victim was the sixth teen to die in East Boston to die in a violent or suspicious manner since September of 2015.

A list of the deaths:

Wilson Martinez, 15, found stabbed to death on Constitution Beach early on Sept. 7, 2015. Officials charge Martinez, a native of El Salvador, was murdered by low-level MS-13 members hoping to move up in the ranks by murdering somebody:

Carlos Melara, also known as "Chuchito" and "Criminal," 19, Henry Josue Parada Martinez, who went by "Street Danger," 20, and Edwin "Sangriento" Gonzalez, 20, all of East Boston, took a younger teen with them to look for Martinez, a native of El Salvador, at the urging of Duran and Noe "Crazy" Salvador Perez-Vasquez, the leader of ELS, another MS-13 gang in the area.

Irvin de Paz, 15, fatally stabbed in the back on Trenton Street around 5:15 p.m. on Sept. 20. Like Martinez, de Paz was a Salvadoran native whom authorities say was murdered by an MS-13 member looking to move up the gang ladder.

Joel "Animal" Martinez, 20, of East Boston, is charged with his murder. He gained his promotion but only after two traditional 13-second beatings by other MS-13 members - normally, an MS-13 murderer would only get one such beating.

Cristofer Perez de la Paz, 16, found shot to death on Falcon Street around 1:30 a.m. on Jan. 10.

De la Paz was a Chelsea resident who was planning to return to his native Guatemala because it would be safer than the Boston area for him. Authorities say that unlike the first two murders, de la Paz's was set in motion by an East Coast conclave of MS-13 leaders, who wanted to ramp up violence against rival gangs, such as the 18th Street Gang in the Boston area (Some nine days after de la Paz's murder, officials say, an MS-13 member opened fire in the Maverick Blue Line station when he saw an 18th Street member on a train).

Blanca Lainez, 19, found beaten to death in the garage of an unfinished house on Princeton Street on June 15.

Angel Ramos, 21, and Jose Hernandez, 16, both of East Boston, have been charged with her murder.

Unidentified male teen, 16, whose body was found in Belle Isle Marsh on Dec. 15. He had been reported missing Nov. 13. Authorities have yet to declare a cause of death or identify him.

Unidentified male teen, found stabbed to death near East Boston Memorial Stadium around 10:45 p.m. on Dec. 24. His identify has yet to be released. WBUR reports police are looking at a possible gang connection to his death.
