California residents who lit illegal fireworks over the July 4 holiday may be in for a nasty surprise in the mail thanks to covert fire department operations.

Homeowner Earl Decastro, 46, was nabbed and booked for involuntary manslaughter, though he has since posted his $25,000 bail.

A large illegal fireworks display, placed in the street by the homeowner, failed and began misfiring toward the home where the child was, police said.
