This prompted someone to call in and give certain details which the police described as "vital information". In July 2005, the BBC broadcast a programme called Body Hunt the Search for Simon Parkes. In 2003, Hampshire Police flew out to Gibraltar and arranged for new searches to take place which involved cadaver dogs and digging in three areas around the South Barracks, around Rosia Lane (where the Naval function was held in 1986) and Trafalgar Cemetery. As Parkes had disappeared on the 12 December 1986, and Grimson was serving aboard Illustrious at that time, parallels were drawn between Parkes' disappearance and the murders. Both had been in the Royal Navy and been killed on the 12 December of each year (19). In 2001, Petty Officer Allan Grimson was convicted of killing two young men. Shipmates later confirmed that Parkes was looking forward to going home for Christmas and that he had also arranged for special dockside passes so that his family could greet him when the ship arrived back in the UK. Parkes had left his passport, all his possessions and Christmas presents behind on the ship with his family later saying that he had written a letter telling them that he would be home for Christmas. Theories ĭeliberate disappearance or AWOL (absent without leave) were originally suspected, with authorities pressing their emphasis on looking for a person, not a body.

This amounted to a 250-man physical search of the area. Parkes' disappearance prompted a search of the areas he was last known to be in.

The witnesses also state that the person appeared to be drunk. Someone fitting his description was seen at the Hole in the Wall pub, part of the Fleet Pavilion (which was hosting a Naval function). Parkes had gone ashore with his shipmates on the 12 December and was last seen at the Horseshoe Bar after telling friends that he was going to get something to eat. This was the last leg of the ship's world tour, Global 86, before she sailed for her home port of Portsmouth. In December 1986, Illustrious berthed in Gibraltar allowing the crew to get some shore leave in. Parkes was a seaman radio operator in the Royal Navy and was serving aboard HMS Illustrious.
