16-year-old allegedly killed parents, sister, family friend minutes before new year

The teenage boy is in custody for the shooting deaths in his parents' home.

— -- Minutes before midnight on New Year's Eve, a 16-year-old boy allegedly used a semi-automatic rifle owned by a family member to shoot and kill his parents, sister and a family friend inside the parents' home in a coastal city in southern New Jersey, the county prosecutor said.

The teen's brother and grandfather apparently escaped harm. They "thankfully left the home and came out OK," Gramiccioni said at a press conference Monday morning.

Police arrived on the scene shortly after receiving a call from inside the home about shots fired at 11:43 p.m. on Dec. 31, a statement from the prosecutor's office said.

The boy was arrested at the scene without incident, Gramiccioni said.

No possible motive was revealed.

"It’s a terribly tragic incident," Gramiccioni said.
