3-year-old boy's death in Hawaii fireworks explosion raises toll to 4; over 20 injured

The blast killed three women and injured more than 20 people, many suffering from severe burns. The extensive injuries reveal the catastrophic nature of the explosion.

Dr. Kevin Foster noted, 'There's something uniquely and particularly horrifying about being burned, especially from this type of injury,' indicating the psychological trauma that accompanies such burns.

Hawaii's leaders intensified calls for crackdown on illegal fireworks, linking the tragedy to inadequate enforcement and stressing the need for greater penalties to prevent future incidents.

The six patients in Arizona have extensive burns, requiring long-term care, with some likely remaining intubated and in comas for months. Their recovery promises to be arduous.
