Thieves who executed a teenage girl on honeymoon in Jamaica may never be brought to justice.

Tamalyn Bundy-Davis, 17, from Whitehawk, Brighton, was found dead in bushes in December last year.

Her wedding ring had been torn from her finger and her body bound to that of her new husband Jermaine Davis.

Both had single bullet wounds to the head.

At an inquest in Brighton Magistrates Court yesterday, the city's deputy coroner Matthew Orde ruled Tamalyn had been unlawfully killed.

But he said he could not establish a clear motive.

Although the ring and passport were missing, police are not convinced robbery was the sole reason for the execution.

Tamalyn's brothers Matthew and Jonathan Bundy are angry at the failure of Jamaican detectives to catch the killers.

After yesterday's verdict they vowed to discover why their sister was slaughtered.

Jonathan, 23, from Woodingdean, said: "It is time to find out the truth."

Tamalyn, of Warbleton Close, met Jermaine, 29, in May last year.

Her family suspects Jermaine had an ulterior motive for marriage - he was a known crack dealer and desperately wanted a British passport.

The couple married in October and Tamalyn's stepfather paid for them to fly to Jamaica, where Jermaine lived, for their honeymoon.

They were reported missing on November 28 after a trip to the British High Commission in the capital Kingston, where they were arranging a residency permit for Jermaine.

Six days later, their bodies were discovered, bound, gagged and hidden in a remote area of the island by a farmer.

Forensic evidence suggested they had been killed elsewhere and dumped.

Jonathan told the inquest he blamed drugs for his sister's death.

He said Tamalyn and Jermaine had dabbled in dealing in Brighton.

After the inquest Jonathan, who is deputy manager at the Prince Regent swimming pool in Brighton, said Jermaine had made his sister happy but her love for him had led to her death.

He said: "At the end of the day, Jermaine has killed her.

"The only reason he married her was to get a passport to get over here. He didn't have anywhere to live and we made him part of our family. We were happy for them.

"Jermaine was heavily dealing crack cocaine. Tamalyn was going along for the ride. She was not an addict.

"I am frustrated by the lack of information but I am determined to try to find out what happened."

Matthew, 20, of Denmark Villas, Hove, who works in customer services, said: "We are not happy with the lack of information from the police but it looks like there is nothing we can do to help try to find her killer.

"I don't blame Jermaine at all because they were in love and she was very happy.

"I don't believe it will ever be solved. There are so many murders in Jamaica and this is just one more to add to the pile."

Detective Sergeant Philip Aldred, of Sussex Police, told the hearing his Jamaican counterparts had yet to establish a motive or find a suspect.

He said the British High Commission was pressing for an up-to-date report on the investigation.

Recording the verdict, Mr Orde said: "Unfortunately there are no suspects and no clear motive. However, it is strongly suspected these deaths are drug related.

"Hopefully eventually the perpetrators of these crimes will be arrested and face justice."
