Six-Year-Old Boy Tragically Killed by Family Pit Bull on Fourth of July

A six-year-old boy died from severe injuries after being attacked by his family's pit bull mix in Florida.
The three-year-old dog had no history of aggression and may have been spooked by fireworks, experts say.
The child was airlifted to the hospital but died from bites to the chest and head.
The pit bull mix was taken into custody by animal services following the fatal attack.
The boy's death is one of several deadly dog attacks in the U.S. so far this year, according to authorities.
