Enron's Jeffrey Skilling Ate Caterpillars and Worms on Long Hiking Trip

An AP article about former Enron President Jeffrey Skilling contemplating suicide is pretty straight forward until you get to the part about Skilling spending two weeks in the Utah wilderness, hiking 30 miles a day:

During that time, he ate caterpillars and worms.

The piece goes on to discuss Skilling's long prison term. What? The former president of Enron spent two weeks hiking 30 miles a day, ate caterpillars and worms and all we get is one sentence?? Did the reporter throw in that line to throw off readers? Why didn't he/she elaborate?
