A hiker on Camelback Mountain was killed Monday while trying to escape a bee attack.
A group of three male hikers were attacked by a swarm of bees off Echo Canyon trail about 3:45 p.m., on a trail that traverses to an area called Ice Box Canyon.
One of the hikers fell to their death about 150 feet when trying to get away. He was pronounced dead at the scene.
"You're running, you're not thinking about what you're doing... except you want to get out of there," said witness Bree Wolfe.
The other hikers took cover in a small crevasse area and waited for firefighters to reach them. They were both stung over 300 times.
A firefighter in a protective bee suit was airlifted onto the mountain to administer help. The firefighter airlifted the two victims off the mountain individually and they were treated in the parking lot.
The victims were transported in serious condition to the hospital, but a full recovery is expected.
"With multiple bee stings, it's just the toxins that go into your body, fortunately it doesn't sound like the two that survived were allergic, but definitely puts a lot of stress on your body being stung that many times," said Phoenix Fire Capt. Scott McDonald.
The rescue firefighter received multiple bee stings but is doing ok.
"Without the use of the helicopter for speed of rescue, there is a good chance there would have been 3 fatalities today," stated McDonald.
"It's shocking to see, we climb weekly, almost every day. There have been suicides but never anything like this," said Wolfe.
No names have been released.
The main trail at Echo Canyon was closed Monday night. Crews are going to try to eradicate the bees before it is reopened.
