update:

CAMDEN, New Jersey (CNN) -- Autopsy results show three boys found dead in a car trunk suffocated, and their deaths have been ruled accidental, Camden County Prosecutor Vincent Sarubbi said Saturday.

Sarubbi said there were no signs of foul play in the deaths of 11-year-old Anibal Cruz, 6-year-old Daniel Agosto and 5-year-old Jesstin Pagan, which he called a "horrible, tragic and unexplainable incident."
