The incident occurred following a two-vehicle accident on the 2000 block of Los Amigos Street around 2:45 p.m.
Police say the black Acura involved in the collision hit a tree. That's when the a limb on the tree broke, unleashing the wrath of a massive bee hive hidden inside.
The drivers, a 51-year-old and 17-year-old female, exited their vehicles to exchange information and were immediately attacked.
Police say the 17-year-old was stung about 50 times, but the 51-year-old bore the brunt of the attack and was stung more than 1,000 times.
"She had thousands of bees on her and she was getting stung," said witness John Weyermuller
Neighbors who tried to rush to her aid were forced back by the bees and finally convinced the 51-year-old to jump into a neighbor's pool, but the bees continued to attack her face and head. A sheriff's deputy managed to get her out of the pool and into his cruiser.
"They were on her, and all over her, you know, you could see her face, her eyes, and things like that, but she was pretty well covered with bees, and they were all over the street," said Weyermuller.
Responding deputies found the 17-year-old covered in bees, and used a fire extinguisher to remove the bees from her body. Both victims were rushed to Verdugo Hills Hospital.
A sheriff's deputy was also stung, but he was not seriously hurt or transported to a hospital.
Firefighters sprayed foam to remove the fallen hive and handle the bees.
Witnesses say it was like a scene out of a Hollywood horror film and that the hardest part was not being able to free the 51-year-old woman from the swarm.
"It was hard, you know, it was hard to see somebody who was hurt, asking for help, and there's really nothing you could do about it," said Weyermuller.
The 17-year-old woman was treated and released Sunday. The 51-year-old woman is expected to be released from the hospital Monday.
