A 16-year-old boy is facing a murder charge in connection to Sunday’s shooting in Chelsea that left one dead and seven others injured, according to authorities.

Chelsea Police and State troopers placed the Lynn teen — who was not identified — under arrest on Monday and he is expected to be arraigned Tuesday morning in Chelsea District Court. In addition to the murder charge, other charges are likely to follow, prosecutors said.

According to police, even though juveniles who are accused of murder are automatically charged as adults under Massachusetts law, they have decided to withhold the teen's name in caution until the criminal complaint is issued.

"I want the community to know that Chelsea Police approached this case with urgency and professionalism from the moment it was called in," Chelsea Police Chief Brian Kyes said. "We cannot and we will not tolerate this level of gun violence, especially when it leaves our young people dead and injured."

According to prosecutors, Chelsea Police officers responded to the area of 120 Washington Ave. at about 2:40 a.m. after receiving multiple 911 calls for a disturbance.

Upon arriving, officers found 19-year-old Pablo Villeda gravely injured and seven other victims — all between the ages of 15 and 22 — with injuries ranging from minor to very serious, authorities said.

Police immediately began providing medical aid to the victims and called for emergency personnel. 

Villeda was taken to Whidden Memorial Hospital, where he was later pronounced dead. The other vitims were taken to the same hospital and Massachusetts General Hospital.

Based on a preliminary investigation, cops said the victims and others were attending a party in a vacant apartment when the shots were fired.

"Almost every open homicide is one witness away from being solved," Suffolk County District Attorney Daniel F. Conley said. "We're grateful to those who stepped forward in this case, but our investigation is still very active. Anyone who has additional information on Mr. Villeda's death or the shootings of six young men and women is urged to share it with police."
