One year ago: Ariel Castro, the man who'd imprisoned three women in his Cleveland home, subjecting them to a decade of rapes and beatings, pleaded guilty to 937 counts in a deal to avoid the death penalty. (Castro later committed suicide in prison.) A gunman went on a rampage at a Hialeah, Florida, apartment complex, killing six people before being shot dead by police. Billionaire Texas oilman George P. Mitchell, considered the father of fracking, died at his home in Galveston; he was 94. JJ Cale, 74, whose best songs like "After Midnight" and "Cocaine" were towering hits for other artists, died in La Jolla, California.
