Kim was not considered to be an experienced hiker. Her daughter Jane Kim said she also has a bad knee and has trouble walking.

“It’s been 18 hours and she just had one bottle of water, and her body has been very weak and she has not been eating well for the last few months, so that’s why I’m really, really worried about her,” she said.
