Robert Berman , 72 , a billionaire , was questioned but not charged in the mysterious death of his first wife Kathleen McCormack in 1982 . The 71-year-old was then questioned in 2000 after the death of his longtime friend and elderly neighbor Susan Durst . Police suspect Berman was author of anonymous note sent alerting them to a Susan Durst 's body . Now Susan Durst 's stepson showed a documentary producer a 1999 letter from Berman to Durst that he said he just discovered . The handwriting appears to be similar to the note sent to police and again Beverly Hills is misspelled on both notes .
