‘Frankenstein’ double murderer linked to 20 other killings could be freed by Christmas

A convicted double murderer linked by police to 20 other killings could be freed by Christmas.

Allan Grimson – dubbed the Frankenstein Killer – has been given a parole date after serving 21 years for the murders of two young men.

Evil Grimson was called a “serial killer in nature if not in number” by the judge at his double murder trial.

The fiend is feared to be behind a string of unsolved murder cases from here to New Zealand – but has never faced further fresh prosecution.

The Sunday Mirror can reveal Grimson, now 64, will go before the Parole Board next month. A release could follow within weeks if he gets the green light.

Grimson was first nicknamed Frank, short for Frankenstein, by Royal Navy colleagues who were struck by his ugly looks.

He was jailed for life in 2001 for the murders of Nicholas Wright, 18, and Sion Jenkins, 20, in 1997 and 1998.

The petty officer lured each victim back to his flat, where he bludgeoned them with a baseball bat in similar attacks a year apart.

When Grimson was convicted of Nicholas and Sion’s murders, police told Winchester Crown Court that they believed the killer may be responsible for 20 disappearances.

When sentencing the twisted murderer in 2001, Mr Justice Cresswell told him: “You are a highly dangerous serial killer who killed two young men in horrifying circumstances.”

Sadistic Grimson admitted to police that he used his position as a naval trainer to identify “young, good-looking” potential victims.

He met victim Nicholas, from Leicester, on a fire-fighting course run by the Navy in November 1997. On December 12, Grimson lured the Navy recruit back to his flat and tried to kiss him.

When the teenager spurned his advances he beat him with a bat before slicing off his ear and cutting his throat.

A year later Grimson met Sion , from Newbury, Berks, in a pub in Southsea, Hants.

They went back to Grimson’s flat, where the killer raped the 20-year-old, tied him up in the bath and beat him to death.

Police probing the earlier disappearance of Nicholas spoke to Navy colleagues who voiced suspicions about their crewmate “Frankenstein”.

The fiend admitted killing Nicholas and also told detectives of Sion’s murder. During the court hearing in 2001 a psychologist said Grimson, then 42, was the worst psychopath he had come across in 250 murders.

The killer has also been linked to the disappearance of a naval rating.

Simon Parkes, 18, vanished 35 years ago in Gibraltar, when he and Grimson were serving together on the HMS Illustrious aircraft carrier.

Simon, from Kingswood, Glos, was a radio operator aboard the vessel when he disappeared in December 1986 following a night out with his crewmates.

In 2002, the Sunday Mirror reported Grimson had confessed to killing Simon but was refusing to help police find the body. He later denied the murder.

In 2019, Simon’s mum Margaret revealed she had written to Grimson asking what had happened to her son, but he denied involvement.

The grieving mum said: “I wouldn’t want him to be out. I think he’s a dangerous person. How can someone with that mentality change?”

Tonight Grimson’s former friend Kim Kaplan, for whom he was best man, echoed Mrs Parkes’ calls for the evil killer to remain behind bars.

She said she did not think Grimson could be remorseful, given the seriousness of the crimes.

The ex-pal, of Gosport, Hants, said: “I don’t think he should get parole – absolutely not. Not with the nature of the crimes and all the people that have gone missing that he’s never admitted to.

“He was an outright animal. To this day it is gobsmacking.”

A Parole Board spokesman said: “An oral hearing has been listed for the parole review of Allan Grimson.

“Parole reviews are undertaken thoroughly and with extreme care.

“Protecting the public is our number one priority.”
