THE DISPATCH
The Beginning
Allan Michael Grimson was said by friends to be kind and helpful. He was a large and imposing man who was nicknamed Frankenstein. Grimson hid his homosexuality since it could have had him discharged from the Navy. He kept this secret and others, until he no longer could.
The Murders
Nicholas Wright
- December 12, 1997
- Portsmouth
Junior rating Nicholas Wright was 19 when his Royal British Navy destroyer, HMS Edinburgh, was docked in Portsmouth. Wright took leave and headed to Joanna’s, a local nightclub. The bar was Wright’s last known location. He disappeared on December 12, 1997.
Grimson and Wright originally met on a fire-training course in November, 1997. Grimson gave Wright his phone number and offered him a ride home. Wright, fearing Grimson was gay, called his family for advice, and nothing came of it. A month later the men shared a taxi back to Grimson’s flat where Grimson sexually attacked Wright. Grimson later claimed the murder was a power kill, not a sexual kill.
It was later revealed that Wright was beaten to death with a baseball bat. His murderer, Allan Michael Grimson, said he punched the air in celebration street killing the teenager. Grimson them slit the victim’s throat and put his body in the apartment bathtub. The killer then wrapped up Wright’s naked body and dumped him. Grimson said he enjoyed the “tingling feeling” he got from the murder.
Sion Jenkins
- December 12, 1998
- Portsmouth
Sion Jenkins was a barman in Portsmouth when, exactly one year after the murder of Wright, he met Grimson at Joanna’s. He accompanied Grimson back to the killer’s flat where Grimson attacked Jenkins. The young man was punched and beaten before, according to Grimson, “agreeing” to have sex.
When Jenkins tried to leave the next morning, Grimson bound him and placed him in the bathtub where he beat Jenkins to death with a baseball bat. Grimson later admitted to covering Jenkins’ head with a towel to avoid a similar mess caused when he murdered Wright. Grimson said he wanted to experience the same “tingling feeling” as the first murder, but said it was not as thrilling.
Jenkins died at the age of 20 on December 13, 1998.
Arrest & Trial
Grimson Arrested
- December 15, 1999
- Portsmouth
Police continued to investigate the cold case of Nicholas Wright. On December 15, 1999, police arrested Grimson and another man on suspicion of his murder. With two days, the second man was released without charges, while Grimson faced a second murder charge. After a day of questioning and a night in the cells, Grimson asked to speak to police. Over the course of hours, he confessed to Wright’s murder.
Wright and Jenkins Found
- December 16 & 17, 1999
- Winchester, Hampshire
Grimson took detectives to the location of Wright’s body. The body of murder victim Nicholas Wright was found in a field next to the A272 at Cheriton on December 16, 1999.
The interrogation continued, and Grimson confessed again.
Sion Jenkins was found December 17, 1999, near to the A32 at West Tisted, less than 8km (5mi) from Wright. Wright was identified through dental records while Jenkins was identified by a palm print. Both men had died from head injuries.
Grimson Convicted, Sentenced
- March 26, 2001
- Winchester, Hampshire
On March 26, 2001, Grimson pleaded guilty in court to both murders. He was given a life sentence with a minimum term of 22 years. Later that year, the Home Secretary increased the minimum to 25 years. He appealed the sentence and on May 28, 2008, his minimum sentence was reduced by three years.
Grimson was a suspect in the disappearance of rating Simon Parkes. Parkes vanished when his ship, HMS Illustrious, docked in Gibraltar on December 12, 1986 on its return to Portsmouth from a deployment to Asia and Australasia. Grimson had served on the same ship as Parkes, and the date December 12, tied Grimson to the murder. Grimson did not confess, and the evidence was too circumstantial for charges.
Grimson’s Location
Grimson was eligible for parole in 2021. It is not known if he was released from prison.
