The mother of a sailor who has been missing for nearly four decades has made a heartfelt plea to the notorious “Frankenstein” killer, believed to be responsible for his disappearance, urging him to reveal the truth about her son’s fate.
Margaret Parkes, aged 80, firmly believes that her son, radio operator Simon, was a victim of Allan Grimson, 66, during a stopover of HMS Illustrious in Gibraltar in December 1986. Despite the authorities closing the investigation into Grimson last December, Margaret remains convinced that the two-time murderer was involved in her son’s vanishing act, expressing her ongoing quest for justice after all these years, even though Grimson denies any connection to Simon’s disappearance.
In a direct appeal to Grimson, Margaret pleaded, “Please disclose what happened to Simon.” She implored the police to reopen the case, emphasizing the need to understand the true motives of Grimson. Refusing to give up hope for closure, Margaret expressed her determination to seek answers and bring Grimson to justice, highlighting the long-lasting anguish and uncertainty she has endured for almost four decades.
Grimson, dubbed the Frankenstein Killer due to his imposing stature and distinctive appearance, was sentenced to life imprisonment in 2001 for the brutal murders of two young men who served alongside Simon on the Illustrious aircraft carrier. His heinous crimes involved luring the victims to his residence before savagely ending their lives, with the dates of the killings coincidentally aligning with the day Simon went missing.
Despite being linked to Simon’s disappearance for over 40 years, Grimson has never faced prosecution in connection to the case. Margaret now prays for closure through an inquest, hoping to receive a death certificate that would provide some semblance of closure regarding her son’s whereabouts. She expressed her urgency for justice and resolution, underscoring the emotional toll and sense of helplessness that has plagued her for decades.
Police efforts to unravel the mystery have included extensive searches in Gibraltar, including at a cemetery and a car park, as they seek to uncover any leads related to Simon’s disappearance. Grimson, however, has persistently denied any involvement in the case, maintaining his stance despite mounting suspicions and public scrutiny.
As the saga continues, Margaret remains steadfast in her pursuit of truth and justice, yearning for answers that have eluded her for far too long. The unresolved disappearance of Simon Parkes remains a haunting chapter in the lives of those left behind, with the hope for closure echoing through the years of uncertainty and pain.
