Peter (45), Doris (42) and Michael Smart (10): The Smarts were shot dead in their Uddingston home in the early hours of 1 January 1958. After the murders, Manuel stayed in their household for nearly a week, eating leftovers from their Hogmanay meal and even feeding the family cat, before stealing some brand new banknotes that Peter Smart had kept for a holiday, and taking the family car and dumping it nearby. Manuel gave a lift in this car to a police officer investigating Isabelle Cooke's disappearance, even telling him that he felt that the police were not looking in the right places.
