3-year-old boy dies, raising death toll in Honolulu fireworks explosion to 4

A 3-year-old boy who died Monday was the fourth person to succumb to injuries from a massive explosion of fireworks on New Year's Eve at a Honolulu home, and a doctor said six others faced long recoveries in Arizona, where they were sent to be treated for severe burns.

The blast also killed three women and injured more than 20 people, many of whom have burns over most of their bodies. Two of the people who were killed had been declared dead at the scene.

The Honolulu medical examiner identified the toddler as Cassius Ramos-Benigno. The cause and manner of death were listed as pending.
