The Daily Oklahoman reports that a fourth storm chaser, Richard Charles Henderson, was killed by the El Reno tornado on May 31.
The other three, Tim Samaras and his grown son, Paul, and Carl Young were killed as they deployed probes in the monstrous tornado’s path to gather scientific data and video from the beast’s interior. But the Oklahoman reports that Henderson was an amateur out “having fun.”
The El Reno has been classified an EF-5, with winds near the surface of 296 miles an hour. It was at least 2.6 miles wide, making it the widest tornado in recorded U.S. history.
