Authorities say a shooting that killed one man and left six other people injured by gunfire happened at a party in a vacant apartment in the Boston suburbs.

Nineteen-year-old Pablo Villeda was identified as the victim of the shooting early Sunday in Chelsea. He was pronounced dead at a hospital.

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.

No arrests have been made.

The investigation is ongoing. Investigators are asking anyone with information about the shooting to come forward.
