A TEENAGER convicted of murdering a pensioner after agreeing to meet his victim for sex is facing a life sentence.
Aiden Jackson tricked his victim David Cowley, 67, into meeting him and took him to a derelict site where he was strangled.
Jackson denied murder during a 21-day trial at Lincoln Crown Court, but accepted he was guilty of manslaughter.
He claimed a second teenager was involved in the killing, which took place at the Ballast Pits, off Mareham Lane, Sleaford.
A jury of six men and five women spent six hours deliberating before returning a verdict of guilty of murder.
Judge Michael Heath adjourned sentence until October 20 to allow for the preparation of a pre-sentence report on Jackson, who was 17 at the time of the killing.
After the verdict, the senior investigating officer Detective Superintendent Stuart Morrison, of Lincolnshire Police, described the case as "complex".
He said: "It was a difficult case to investigate. It was not made easier by being given different versions of what happened.
"However I have been satisfied all along that the fatal attack on David Cowley was at the hands of Aiden Jackson and no one else.
"I have spoken to David Cowley's family and they are pleased with the verdict. They say that this is a milestone and a chance to move on."
The jury heard that Jackson, whose only income was his £30 a week education maintenance allowance for attending an FE college, "strung along" Mr Cowley into believing he was interested in gay sex with the pensioner in return for cash and mobile phone top-ups.
They met at Sleaford Railway Station and Mr Cowley, of Coningsby, gave Jackson a lift to the Ballast Pits in his Smart car.
Jackson then strangled the old man who was unable to fight back because of his poor health caused by asthma and a stroke.
Jackson then took his victim's car, together with his money, phone and a ring.
Jackson spent the next day driving around in the Smart car before crashing into a parked vehicle and abandoning it.
He later took his sister and some friends to view the body alongside a lake at Ballast Pits on the outskirts of Sleaford, Lincs.
Jackson made a second trip to the Pits with his mum, who called police as a result of what she saw.
Jackson was arrested after he was found hiding inside his home.
He initially claimed to have found the body, but later said he carried out the killing with another 17-year-old.
That boy was arrested for murder, but no charges were brought against him.
The jury was told Jackson was a habitual liar and petty thief, but his defence counsel, William Harbage QC, suggested he was "a 17-year-old prat" rather than a cold-blooded killer.
