(AP Photo/Orlando Sentinel, Joe Burbank, Pool, File) (Newser) – The estranged wife of George Zimmerman said today she thinks her husband has unraveled since he was acquitted in the fatal shooting of Trayvon Martin. "I don't know who George is anymore," Shellie Zimmerman said on Katie Couric's show Katie. After his murder trial, he became unpredictable and "a pacing lion," she said. "I like to think I married a person who was a good person, and going through the past year and a half, I don't know how that changes a person, or how a person's spirit breaks, but it certainly seems that's what happened to him." Later, she said: "He does seem like a ticking time-bomb." Shellie Zimmerman said she doesn't think her husband intended to kill the 17-year-old Martin in February 2012. He has said he fired in self-defense. Since his trial, Zimmerman has had several brushes with the law, including an arrest this week on charges that he threatened his girlfriend with a gun. His attorneys say he will be acquitted.
