Elliot Turner fancied himself as some form of celebrity in the bars and clubs in the affluent areas of Bournemouth and Poole.

Dubbed ''All-Talk Turner'' by his friends and described as full of ‘gangster bravado’ by his own father, Turner led the life of a supposed playboy with money, girls and drink around the clock while boasting of the cash he had.

But the flash lifestyle hid an immature, manipulative, jealous and violent young man who could not handle rejection - especially from women and, in particular, from Emily Longley.

Turner ran with a crowd of other young men - many of them from wealthy families - who called themselves The Firm.

They spent time drinking £180 bottles of Grey Goose vodka around the millionaires' enclave of Sandbanks or the wealthy area of Clanford Cliffs.

Turner was often spotted pulling up in his black Mini Cooper and told anyone who would listen that he had had affairs with reality TV stars and even spent time in the Priory clinic to kick a cocaine habit.

Women were only referred to as birds or in Emily's case, as the volatile relationship hit the rocks, bitch or much worse.

But many of his friends knew that Turner was a boaster and those who gave evidence in his trial all said they never took a word of what he said seriously - including his boast that he had killed Emily with a mallet a few days before he actually strangled her.

Elliot Turner was the son of a wealthy jeweller and he worked part-time for him at the shop the family owned in Bournemouth called R E Porter.

Born in Birmingham in 1991, he moved south with his family in 2000 when they took over the shop from his grandparents.

University beckoned but he dropped out of Southampton Solent University after less than a term.

Parties and women back home were now the major part of his life.

He met Emily Longley in December 2010 and said the pair hit it off immediately and it appears the relationship worked at first, with both saying they loved each other.

But Emily was a young and vulnerable girl who had suffered from eating disorders and health and emotional problems in Auckland, New Zealand, where she had emigrated from Bournemouth with her family when she was nine.

She had returned to England eight months previously to study for a business national diploma at Brockenhurst College in Hampshire, and worked part-time at Top Shop in Bournemouth.

Very good-looking and with a bright and friendly personality, Emily attracted the attention of men and Turner was unable to handle it.

Soon after they got together, he was already showing signs of becoming obsessive and Turner had form in this department.

He had received a harassment warning letter from police in January 2008 when he was 16 telling him not to contact an ex-girlfriend after he bombarded her with texts and emails when she ended the relationship.

One friend told the trial that after a girlfriend left him, Turner said he wanted to suffocate her with a pillow.

The situation got worse when Emily returned to New Zealand to visit her divorced parents Mark and Caroline.

Turner was upset about pictures with other men she posted on Facebook and he became obsessed with the idea that his girlfriend should show him more ''respect''.

His fears multiplied when Emily was found out to be texting and seeing other men on her return to England.

Turner was now violently angry and even though he painted a picture of only looking out for Emily's best interests, the threats to kill her became almost daily.

Police found a note Emily had written to Turner when the pair were on holiday on the Isle of Man in late March which showed how Turner behaved towards her.

She wrote: ''I love you. Don't say you will kill me. Stop talking about your ex-girlfriend and stop being so constantly aggressive. Be more cool because that's so much more hot.''

He finally snapped when Emily went out dressed, in his words, like ''a whore'' on the evening of May 6.

He thought they had patched up their relationship a few days before and were boyfriend and girlfriend but Emily finally wanted out.

Fed up with his constant anger and questions, she threw drinks at him that night in the Cafe Shore bar and Turner assaulted her.

His friend Tom Crowe was the last person to see Emily alive and presciently he told one of Turner's neighbours he feared that Turner would kill her.

That night the pair rowed and Turner used a pillow to smother Emily - imprinting her make-up on the pillowcase - and then using his arms to strangle her.

His doting parents Anita and Leigh, whom Turner used for cash to fund his lavish partying, loved their son so much they tried to cover his crime.

Leigh destroyed Turner's letter confessing he had strangled her and Anita took the jacket from the bedroom where, the prosecution said, the letter was.

His mother even delayed calling an ambulance as Emily lay dead in the bed of the house in Queenswood Avenue, so that Turner could cover his tracks and allow the family to concoct a story.

But Turner had left too many clues and too many threatening text messages and told too many friends of his obsessions and violent thoughts.

The police were immediately suspicious and acted swiftly to get the evidence they needed to charge him.

The bugging of the family home that May and June was the most damning evidence as the three discussed what they would say to the police, with Elliot Turner leading the discussion and orchestrating the ''fabricating of evidence''.

It was a telling example of the arrogance of a young man who thought he could manipulate his parents, the police and his friends to get away with murder.

Elliot Turner's defence team tried to get the bugging evidence ruled inadmissible at the start of the trial but failed.

All three in the witness box were forced to listen to their scheming and they had little answer to the incriminating conversations that sealed their convictions.
