A man strangled a teenage girl to death before discarding her body in a pond after she rejected his sexual advances, a judge has ruled.
Swansea Crown Court heard how Lewis Haines, 31, went on to murder Lily Sullivan, who was just 18, after meeting her in a nightclub in Pembroke in west Wales in December.
The pair kissed after meeting in the Out nightspot on 16 December and later went to a nearby alleyway together where they became more intimate.
Sullivan was later found face down and topless in the Mill Pond, a two-mile-long freshwater reservoir near the town, the court heard.
After murdering Ms Sullivan, Haines walked past his victim's mother as she waited to pick her daughter up from a nearby garage.
Haines, a father-of-one, has confessed to murdering Ms Sullivan but denied sexual misconduct.
But after a trial of facts, Judge Paul Thomas QC concluded Haines had killed the teenager after she rebuffed his sexual advances.
“It is clear that Lewis Haines wanted to ensure that Lily died. His intention was to silence her,” the judge said.
“He didn't want anyone to know what had happened in the lane. I am sure, however, having been in that lane for some time with Lily and having had intimate contact with her up to a point, Lily decided that she was going home to meet her mother.
“She made it clear from the phone call if nothing else to her mother that she did not want the intimacy between her and Lewis Haines to go as far as sexual intercourse.
“Fuelled as he was by drink, I am sure that Lewis Haines was frustrated by this because he had expectations and hopes that it would go further.”
Haines claimed Ms Sullivan threatened to accuse him of rape and he did not want his partner and family to learn what had happened.
William Hughes QC, prosecuting, had argued that Haines “showed sexual interest in Lily” from the time he met her in the venue.
The court heard how Haines admitted they kissed in the alleyway where her jacket, mobile phone and tobacco were later found.
The teen's call to her mother at 2.47 am had been cut off mid-sentence and Mr Hughes said it was the Crown's belief that “Lily was attacked at that point”.
He also said that it was their case that Ms Sullivan's cream-coloured lace crop top had been removed “forcibly” before she was pushed in the water.
John Hipkin QC, defending, said there was no forensic evidence of sexual contact between the pair or evidence the top had been torn from her body as it remained intact.
Haines claims he tried to pull Ms Sullivan out of the water, but the judge rejected this saying he had made no attempts to save her.
The defendant, who was wearing a white shirt and had a shaved head, held a hand to his head and looked up at the ceiling as the judge spoke.
Haines, of Flemish Court, Lamphey, will be sentenced on Friday.
The court heard how Anna Sullivan, who is the mother of Lily, was talking to her daughter on the phone as the attack started but the phone line cut out, with her mother attempting to call her daughter 30 times but to no avail.
