EXCLUSIVE: Part-time model Lily Cartier, 53, stole powerful drugs from work and slipped them into food and drink she prepared for John Sharrard, who was more than 20 years her senior. Mr Sharrard's relatives became concerned when he suddenly began slurring his words, dribbling and was unable to walk properly but neurologists were stumped as to the cause of his decline. It wasn't until Mr Sharrard's brother, Mike, a molecular biologist, and other family members, raised concerns to doctors that a toxicology test was taken and the horrifying truth was revealed.
