THIS is the chilling moment a teen walked down the street with her killer moments before he strangled her and dumped her body.
Lily Sullivan, 18, was found half-naked in a pond in Pembroke, Wales, after she rejected Lewis Haines' sexual advances.
Haunting CCTV footage showed her walking through the quiet streets with the 31-year-old after they met in a nightclub.
Lily can be seen engaging in conversation with her killer and handing him her bag in her final moments.
The pair then made their way to an alleyway where they became more intimate before the teen rebuffed Haines.
He then strangled Lily in a bid to "silence" her and "forcibly" removed her lace top before pushing her in the water.

Further CCTV then shows the moment Haines walked past Lily's unwitting mum as he fled the murder scene.
Anna Sullivan can be seen glancing at the killer as he passes her car as she waited to pick her daughter up in a nearby garage.
Tragically, Lily had called her mum at 2.47am telling her: "I'll be there now mam. I'm on my way. I'm a couple of minutes away. I'm nearly there."
The call then disconnected mid-sentence as Haines pounced - with Anna frantically trying to call her daughter back 30 times.

The footage was released by the Crown Prosecution Service ahead of Haines' sentencing tomorrow.
Swansea Crown Court heard how after Haines murdered Lily, he rushed home to his girlfriend and told her: "I have strangled somebody.
"They are in the Mill Pond. I've been in the Mill Pond."
He then drove with his partner to his mother's house while he was "crying" and "hysterical".
After he was arrested, the monster asked cops: "What the f*** have I done?"
He admitted grabbing Lily's neck with both hands before he "threw her sideways" and caused her to fall into the water.
The court was told Haines claimed he strangled Lily because threatened to accuse him rape.
But Judge Paul Thomas QC concluded Haines had killed the teen after she rebuffed his sexual advances.
He said: "It is clear that Lewis Haines wanted to ensure that Lily died. His intention was to silence her.
"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 will be sentenced tomorrow.
