The woman accused of poisoning her husband with eye drops once shot him in the back of the head with a crossbow. Police have reopened an investigation into the bizarre incident at the home of millionaire Stephen Clayton and his 52-year-old wife, Lana, two years ago. Lana told police she was having trouble loading a crossbow. She said she took it into the bedroom where her husband was sleeping. Then she claimed it accidentally went off and a piece of the bow struck him in the back of the head.
