Two rock climbers died after falling from the El Capitan granite cliff in Yosemite National Park on Saturday, according to reports.
It was the second fatal incident in Yosemite National Park in a little over a week.
Hans Florine, Honnold's partner in a previous record-setting climb in 2012, watched from a wheelchair after being injured in a May 4 fall from the Nose. He said Klein was known for his speed and knowledge of El Capitan.
Richards is not sure if the climbers were "hands free" or using ropes.
