Jury selection for the trial of legendary philanthropist Brooke Astor's only son starts today. Anthony Marshall, 85, oversaw his mother's estate and has been accused of swindling as well as mistreating his ailing mother. According to the Times, much of the case surrounds whether Astor was competent when she signed a 2004 codicil to her will, giving Marshall her estate; prosecutors will apparently cite a 2000 letter written by Marshall that "in which he told vivid anecdotes about her fragile mental state." The Post is excited for the trial (perhaps hoping for another "Bad Heir Day"), which is "expected be a two-month-long trial, which will be rich with boldface names and palace intrigue and focus a spotlight on Astor's painful final years." However, it's unclear how many boldface names will testify; a source told the Daily News, "David Rockefeller and Henry Kissinger want out of this whole matter. They are just not interested. They never expected it to go this far. It's Annette [de la Renta, Astor's friend] who is out for blood." Marshall, a former Marine, has called the charges against him a "malicious jihad."
