The care worker was last seen alive on a night out with friends A woolpacker from Porthmadog has been sentenced to life in jail and must serve a minimum 25 years before parole for the murder of Ffion Wyn Roberts.
Iestyn Davies, 54, was convicted by a 10 to 2 majority verdict after he denied killing the 22-year-old care worker.
The judge at Caernarfon Crown Court described Davies as “very dangerous” and “calculating and devious”.
Ms Roberts’ body was found in a drainage ditch on 10 April last year.
The jury deliberated for 21 and a half hours before reaching a verdict.
Mr Justice Lloyd-Jones told Davies: “I’m sure this murder has a sexual motive which must have increased Ffion’s ordeal.
“This is a foul crime which involved the wicked taking of a young life”
Mr Justice Lloyd-Jones
“You have been found guilty on the clearest and the most compelling evidence”.
“This is a foul crime which involved the wicked taking of a young life”.
The trial heard case against Davies was that he was in Porthmadog town centre early on the morning Ms Roberts was killed.
He was seen on CCTV around 0400 BST, but disappeared from view shortly before Ms Roberts was last seen.
Items of clothing from the dead woman were then linked to him by DNA evidence.
Iestyn Davies must serve a minimum of 25 years before parole The court heard tracksuit bottoms, a training shoe and Ms Roberts’ handbag were found because they got lodged in the mechanism of sluice gates not far from where her body was found.
Describing Ffion as easy prey because she was drunk, the judge added: “It was a terrible mischance that your paths crossed, on an impulse you saw your chance and you took it.”
