Allan Grimson, a former Royal Navy petty officer serving a life sentence for the murders of two young sailors, has been given an additional 22-year jail term after being convicted of sexually assaulting four other men in the 1990s.
Grimson, 67, was found guilty in July of rape and indecent assault against a teenage naval rating, as well as indecent assault charges involving three other male complainants, with offenses occurring between February 1994 and November 1999. He was also convicted of taking indecent photos of a child victim.
The judge warned Grimson that he "remains a danger to the public," citing the similarity between the current offenses and his previous convictions for murder. The court heard Grimson had told police that a sailor he is now convicted of sexually assaulting was "lucky to be alive" and that "If you're going to rape somebody, to get away with it, kill it."
Grimson was jailed for life in 2001 for the murders of Nicholas Wright, 18, and Sion Jenkins, 20. He killed Wright on December 12, 1997, and Jenkins between November 1, 1998, and December 18, 1999. The court heard Grimson invited both men to his flat and killed them with a baseball bat when they rejected his sexual advances, subsequently dumping their bodies a year apart in the 1990s.
During sentencing, Judge Paul Dugdale stated that Grimson posed a "significant risk to members of the general public of serious harm," based on the "link in your psychology between sexual assaults and an urge to inflict serious violence." The judge added that Grimson would not be eligible for parole until he had served 13 years of his new sentence, which would be just before his 80th birthday. He will remain in custody for life unless the parole board deems it safe for his release.
Grimson, then a Petty Officer Marine Engineering Mechanic and an instructor at the Royal Navy Firefighting School in Portsmouth, used his authority over young naval recruits. The assaults occurred in the same flat where he murdered Wright and Jenkins. The court also heard that Grimson had been with his victims at the Portsmouth nightclub 'Joanna's' before taking them back to his flat.
Grimson had denied the latest charges, claiming his trial was a tactic to prevent his release on parole. He had previously been cleared to move to an open prison as a step towards release before being charged with these offenses.
