The family of murdered teenager Tamalyn Bundy-Davis have told how the last few months of her life were plagued by drug addiction.

Tamalyn, 17, from Whitehawk, Brighton, was murdered while on holiday in Jamaica last month with her new husband Jermaine Davis.

The couple were shot in the head and their bodies dumped in a field 18 miles south of the capital Kingston. Their hands and feet were bound with masking tape and they had been gagged.

Tamalyn's wedding ring had been stolen but police are not yet certain of a motive.

Tamalyn met Jamaican-born Jermaine, 29, in May, when she was just 16.

In an interview with a national newspaper, Tamalyn's brother and father said within months of meeting him she had become a crack cocaine addict.

Her father Graham Bundy, 51, said she thought herself to be in love and planned to start a family with Jermaine, who was also keen to get married so he could remain in the UK.

Unaware she had become hooked on drugs, Mr Bundy, who lives in Hertfordshire, signed a consent form.

They were married in September at Brighton and Hove register office and flew to Jamaica on honeymoon weeks later.

Tamalyn's brother, John, 23, from Brighton, told the newspaper he boycotted the wedding when he discovered she was taking drugs. Like the rest of the family, he watched helplessly as his sister began to change.

He said: "She was such a beautiful girl and she had everything ahead of her. Suddenly she was a crack addict. I felt my heart break when I discovered what was going on."

Since the death of her mother in January, John said Tamalyn was finding it difficult to cope.

He said: "She just wanted to stay shut away.

"Then one night in May she decided to go out with some friends and that night she met Jermaine. She was at her most vulnerable. Six months later she was dead."
