MURDER jurors have heard details of Steven Grieveson’s criminal career before he was convicted of killing three teenagers.
The serial killer murdered David Hanson, 15, Thomas Kelly, 18, and David Grieff, 15, during a four-month killing spree in Sunderland between 1993 and 1994.
He denied he was the killer, who strangled his victims before setting their bodies alight, but was convicted by a jury after a trial in 1996, and has since admitted what he did.
The 42-year-old is now on trial at Newcastle Crown Court for the murder of 14-year-old Simon Martin in 1990, whose body was found in a derelict house in the city after he went missing in May that year.
Grieveson admits he killed the schoolboy, but denies murder on the grounds of diminished responsibility.
Simon went missing after failing to return to his Southwick home on May 18, 1990.
His body was discovered in the derelict house on the Roker seafront eight days later, on May 26. He had been beaten and strangled.
Prosecutor William Lowe told jurors Grieveson has convictions for 61 offences between 1984 and 1996.
During that time he served prison sentences for creating a bomb hoax and robbery.
On October 22, 1990 Grieveson was sent to a young offenders’ institute for four months for taking a vehicle without consent.
On September 2, 1991 he was jailed for six months for driving while disqualified and other road traffic offences.
On February 26, 1993 Grieveson was given another six months behind bars for further motoring offences.
On June 4, 1993 he was given six months for burglary.
On May 6, 1994 Grieveson was jailed for six months over a bomb hoax call.
On September, 16 1994 he was given a total of 27 months behind bars for offences including robbery and burglary. It was while serving the last sentence Grieveson was arrested for the three murders he is convicted of.
