THE man accused of murdering Simon Martin 23 years ago has admitted he killed the schoolboy – but denies murder.
Steven Grieveson is charged with killing 14-year-old Simon Martin in 1990. His trial began today.
The teenager’s body was found in a derelict building on Sunderland seafront, but his killing remained a mystery for 23 years.
During a hearing at Newcastle Crown Court in February, via videolink to HMP Frankland, Grieveson, 42, pleaded not guilty to a charge of murder.
Simon’s body was discovered in Gillside House on Saturday, May 26, 1990, eight days after he disappeared from his family home in Southwick.
In the days that followed, his father Robert appealed for help to catch the person responsible for his son’s death.
Police carried out fingertip searches of the grounds surrounding the three-storey house, as well as nearby Roker Park in a bid to discover what had happened to the Monkwearmouth School pupil.
A post-mortem examination showed Simon had suffered brain damage after blows by a blunt instrument.
After his death, detectives appealed for people who used the then derelict Gillside House to come forward with information.
They also appealed to Wearsiders who might have been in Roker Park close to the time the teen’s body was discovered.
More than 22 years later, in November last year, the Crown Prosecution Service announced it was charging Grieveson with Simon’s murder.
At February’s hearing, Judge James Goss QC told the court a trial would take place to determine whether Grieveson is guilty of murder or manslaughter.
