A Birmingham dad was found dead in Jamaica after he was snatched from a car at gunpoint.
Businessman Keith Murrain's kidnappers cut his throat, his family told the Mail.
The 54-year-old, from Edgbaston, was kidnapped on Friday, just after he had flown to the Caribbean island.
The father-of-three's body was found 24 hours later in a shallow grave in a field near Spanish Town - dubbed Jamaica's murder capital.
Mr Murrain's close friend Howard Reid, a Birmingham barrister, said last night: "Whoever did this are scum, filth, savages and I hate them.
"I curse them, I really, really do.
"The savagery, the lack of humanity, the coldness.
"To look a man in the eye and cut his throat.
"I really do hate them."
Mr Murrain was travelling away from the capital Kingston's Norman Manley Airport in a hire car when he was abducted and bundled into a waiting vehicle.
It was unclear whether he was robbed before he was killed.
The former Great Barr Comprehensive School student had built-up a thriving business exporting engineering parts to Jamaica and Trinidad.
He was a regular visitor to Jamaica, where he reportedly had a home in the gated Caribbean Estates Community, said to boast "Fort Knox-esque security".
Reports from the island said police were following several leads over the killing.
But his family in Aston said they could not understand why he had been murdered.
Mr Murrain's mother Josephine, along with his three brothers and two sisters, were being comforted by West Midlands Police liaison officers yesterday.
His sister, Jenifer Morrain, said: "We, as a family, want justice.
"Why kill him?
"Why not just rob him?
"I want the people who did this to hang."
"Keith was a well-known, born and bred British businessman, loved by everyone who knew him.
"His untimely death has caused a lot of distress to his family, friends and colleagues.
"He was able to secure a lot of contracts in Jamaica and bring a lot of business to the Jamaican economy.
"What happened to Keith will have a major impact on people doing business or going on holiday to Jamaica.
"The latest incident involving someone being targeted shortly after arriving on the island underlines the need for everyone to be vigilant when departing the airport."
Jenifer added: "Everyone knew Keith and everyone looked up to him.
"He was the life and soul of the party.
"When his body is brought back, it will be the biggest funeral Birmingham has ever seen."
Mr Murrain's mother, originally from Montserrat in the West Indies, is now trying to fly with his ex-partner to Jamaica.
She has been in contact with the British High Commission in Kingston, which has pledged to provide police protection during her time in the Caribbean.
And Mr Murrain's devastated brother Samuel hit out at the violence and crime that has blighted Jamaica.
In 2005, the island, which retains the death penalty, had the world's highest murder rate, with 1,674 killings: a staggering 58 per 100,000 people.
In 2011, the island, with a population of 2.7million, endured 1,124 murders, 1,322 shootings, 738 rapes and 3,033 robberies, the US Bureau of Diplomatic Security revealed.
Fighting back tears, 35-year-old Samuel said: "My brother is the latest in a line of businessmen to be murdered.
"It has to stop.
"He went to sort out his business affairs and he was kidnapped and had his throat cut.
"My brother was a prominent businessman - he wasn't rich, but he was doing alright. He was not struggling.
"My mother's not very good.
"Keith helped her a lot. He supported her, but now she has no support."
Samuel described the killing as a "set up".
Mr Murrain rang barrister Mr Reid five days ago to say he was going on a business trip and would be back in two weeks.
The 59-year-old, currently supporting the family, described Mr Murrain as his "little brother".
Battling to keep the anger at bay, he said: "This has torn a hole in all our lives.
"My heart has been destroyed. We love him - that is not exaggeration, it is not hyperbole.
"He was an intelligent and charming man.
"He showed kindness to everyone, he loved his mother and father.
"We would sit at a table and eat and laugh. He had a razor-sharp wit. He liked a bit of football and table-tennis.
"He also liked world history and world politics.
"What has happened is beyond comprehension - to have him killed, then thrown away like rubbish."
Following the killing, a senior officer in Jamaica's police force urged those flying back to the island to be careful who they inform.
He said: "Crimes committed against people returning to the island are often organised by people who know them and the time and date of their return."
A Foreign Office spokesman said: "We are aware of the death of a British national in Jamaica and are providing consular assistance to the family at this difficult time."
