Authorities say a 16-year-old boy has been arrested on a murder charge in connection with a weekend shooting that killed a man and left six other people injured by gunfire in the Boston suburbs.

Police arrested the boy Monday night in the Chelsea shooting that killed 19-year-old Pablo Villeda. The boy, who's from Lynn, is scheduled to be arraigned on Tuesday. It's unclear if he has an attorney who can comment on the charges.

Police say the shooting happened early Sunday during a party in a vacant apartment. Seven other people were taken to the hospital with injuries not considered life-threatening. One of them had injuries unrelated to the gunfire.

The surviving shooting victims are three females, ages 15, 17 and 18, and three males, ages 15, 18 and 22.
