TV Lawyer's wife murdered UPDATE

CNN is reporting a 16 year old has been arrested for the murder of Pamela Vitale, wife of lawyer David Horowitz...popular for being a legal analyst on cable news stations. Things got even weirder in this case when Horowitz's high profile rich-woman-kills-husband case was declared a mistrial due to his circumstances. And now a 16 year old is involved? something seems fishy to me. I'm no detective but doesn't it seem possible that a psychotic rich woman would send a 16 year old to kill her own lawyer's wife to grab a few extra months outside of federal prison?
