After removing her corpse from the canvas sack and beginning the post mortem examination, pathologist Keith Simpson told Ranson he was certain that Rivett had been killed before her body was placed in the sack, and that in his opinion the lead pipe found at the scene could be the murder weapon. Her estranged husband, Roger, had an alibi for the night concerned, and was eliminated from police inquiries. Other male friends and boyfriends were questioned and discounted as suspects. Her parents confirmed that Sandra had a good working relationship with Lady Lucan, and was extremely fond of the children. Meanwhile, Lucan had yet to make an appearance, and so his description was circulated to police forces across the country. Newspapers and television stations were told only that Lucan was wanted by the police for questioning.
