A teenage student was murdered after being lured away from her friends at a party, a court has heard.

Former Bexhill schoolgirl Rebecca Storrs, 18, had been on a night out with her older sister Victoria in their home town of Bridgend, south Wales, on Friday 5 March last year.

But the jury at Cardiff Crown Court heard that the pair had been separated after an argument and Rebecca went off with some friends to a house party in the Wildmill area of the town.

Rebecca, who was described as an "attractive and modern girl", phoned her younger sister Laura at home in Westminster Way, Bridgend, to tell her that she was going to the party in the early hours of the Saturday morning.

The court then heard that outside the party the schoolgirl bumped into the accused, Marc James Shillibier, who told her that he could supply her with whatever drugs she wanted.

Stephen Hopkins QC, prosecuting, said Shillibier, 33, made this claim up to "successfully and tragically lure Rebecca away from her friends".

He added that Rebecca, an ex-pupil at St Richard's Secondary School, Bexhill, was never seen alive again by anybody other than Shillibier.

Rebecca's partially-clothed body was found the next morning semi- submerged" in the River Ogmore, Bridgend, behind a Bookers cash and carry.

Mr Hopkins said: "She had been strangled. The attack was sexually motivated and she died because she resisted that attack."

Shillibier, who was lodging with friends in Bridgend at the time, denies murder.

The case continues.
