A man sawed at his arms at a Los Angeles–area Home Depot on Wednesday as horrified customers watched the scene play out, helpless to stop it. “He just began sawing away,” said West Covina police Cpl. Rudy Lopez. “He was pretty much intent on doing what he did.” That’s for sure: he cut all the way down to the bone. Customers called 911, and paramedics arrived just as he was passing out. Police said the man had undergone surgery Wednesday afternoon, but there have been no more updates on his condition.
