THE teenage stepson of murdered Jock Straiton is pleading with police to find his dad’s third killer.

Adam Gerrard, 17, contacted The Chronicle after we published a story last week calling for the case to be reopened.

Sunday, August 9, marks the first anniversary of the day 59-year-old Mr Straiton, whose real name was James, died.

He had been attacked outside his home on Park Road in Winnington two weeks earlier.

Nigel Goolding and Joshua Spruce, both now 20, are serving life sentences after being convicted of murder at Chester Crown Court in April.

Wincham man Paul Blower, also 20, was found not guilty and freed after eight months in custody.

Adam, who lives in Barnton, said: “Even the judge said there was a third man involved, but the police won’t reopen the case.

“Why? I don’t understand.

“I’m going to try my hardest to get them to reopen it, and try to get them to find the third man that jumped on my dad’s head.

“It is sickening to think someone has done such a thing and the police just sit back and don’t seem to care.”

Det Insp Helen Spooner, who led the investigation, said since the end of the trial no new evidence has come to light which would “give grounds to continue the investigation”.

Adam claims justice will only be done to his stepdad when the third killer is caught and punished.

“I never had a dad and when I was around a year old James came into my life,” he said.

“When I was around 12-years-old I found out he wasn’t my biological dad, but it only made us become closer.

“I can’t stand the thought that one of his killers is walking the streets. It’s not right.”
