A MAN who strangled a teenager and left her in a reservoir after she refused to have sex with him has been jailed for life with a minimum term of 23 years and four months.

Lewis Haines, 31, murdered 18-year-old Lily Sullivan after he met her inside a nightclub in Pembroke, south-west Wales, just before Christmas last year.

The pair had kissed after meeting in the Out nightspot on December 16 and later went to a nearby alleyway together where they became more intimate.

Swansea Crown Court heard Miss Sullivan was later found face down and topless in Mill Pond, a two-mile-long freshwater reservoir near the town.

After murdering the teenager, Haines walked past his victim’s mother as she waited to pick her daughter up from a nearby garage.

Father-of-one Haines admitted murdering Miss 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.

Judge Thomas said it was clear that after spending around an hour in an alleyway together, Haines had become “frustrated” and attacked Miss Sullivan.

Her tobacco tin, mobile phone and leather jacket were later found strewn on the ground in the lane.

Haines made Miss Sullivan walk to the lake, a short distance away, and “forcibly” removed her cream lace top.

He later claimed Miss Sullivan had threatened to accuse him of rape.

Judge Thomas said part of the defendant’s story held an “element based in truth” and that he had a “great deal to lose”.

At the time, Haines was going through family court proceedings to have access to his child, and had a girlfriend.

“He strangled Lily in order to prevent her telling people he had tried to get her to go further than she was willing,” Judge Thomas said.

“His intention was to silence her.

“He didn’t want anyone to know what had happened in the lane.”

Miss Sullivan’s social media contained a number of poignant posts about misogyny, sexual violence and women being killed by men.

One of her Instagram stories contained a photograph taken of floral tributes left for Sarah Everard with a sign that read: “She was just walking home.”

Another post several weeks later listed 80 women who had been killed by men since Miss Everard was murdered by Met Police officer Wayne Couzens.

Others included words such as “Men shouldn’t be making laws about women’s bodies”, “Maybe not all men, but all women”, and a guide on how to recognise if you have been spiked.
