A postal carrier and a homeowner were injured by the swarm of bees in the 3800 block of Hitchcock Drive on the morning of May 14.

Several people were stung and at least two dogs were killed by the swarm. A veterinarian treating the animals said she stopped counting after pulling out 50 stingers from each dog.

While trying to cover the story, KPIX 5 reporter Da Lin said the swarm was so relentless that he couldn’t get out of his van.
