Chelsea MS-13 gang member pleads guilty to conspiracy to commit murder, other charges

A member of the MS13 gang from Chelsea pleaded guilty Thursday in federal court for his involvement in the fatal shooting of a mother of three who was killed by a bullet intended for a rival gang member, according to the US Attorney’s office.

Bryan Barillas, 20, a Guatemalan national also known by the street name “Chucky,” pleaded guilty to racketeering conspiracy charges involving murder, attempted murder and conspiracy to commit murder, prosecutors said in a press release.

Under the terms of a plea agreement, Barillas would serve 22 years in prison, and be subject to deportation afterward, if a judge accepts the agreement, the release stated.


He pleaded guilty to his role as a co-conspirator to shoot a rival gang member on Oct. 18, 2014. Barillas provided a weapon to another alleged MS13 member, who shot at a rival gang member, prosecutors said.

But the bullet missed the gang member and instead killed the woman, “ . . . an innocent bystander who was looking out a nearby window of a room she shared with her three children,” according to prosecutors.

Barillas, who was a juvenile at the time, also admitted to being present during the shooting. He also pleaded guilty to his role in three other violent incidents: conspiracy to kill a MS13 member in Chelsea believed to be cooperating with authorities in April, 2015; stabbing and attempted murder of a rival gang member in Chelsea on May 26, 2015; stabbing and attempted murder of an individual in Chelsea on Sept. 8, 2014, the release stated.

He was one of 61 people charged after a three-year investigation into alleged leaders, members, and associates of MS-13, a violent street gang with roots in Central America. He is the 20th defendant to plead guilty, the release stated.
