An ISIS-linked gang who brutally stabbed and battered a British couple to death then threw their bodies to crocodiles have been found guilty of their murder.

World renowned botanists Rod Saunders, 74, and wife Rachel, 63, were ambushed in South Africa whilst out searching for rare gladioli flowers in remote mountains.

The devoted couple who were married for over 30 years and lived in Cape Town met a horrific end whilst setting up camp beside a forest dam in a national park.

A court heard how they were viciously tortured for Rachel's gold credit card PIN number and bank account details before being hacked, stabbed and battered to death.

They were then disposed of after being cocooned in their sleeping bags and thrown off the Tugela River Bridge in the Ngoye Forest National Park to Nile crocodiles.

Just 48 hours earlier the botanic experts were being interviewed by BBC presenter Nick Bailey for a Gardeners World special in the remote Drakensberg Mountains.

Shortly after the BBC2 wildlife documentary team and the horticultural experts parted company the pair were attacked after parking their 4x4 to prepare to pitch camp.

Durban High Court heard how first gang ringleader and Muslim convert Sayefundeen Del Vecchio, 44, acting alone had identified them to his wife and lodger by phone as a 'good hunt'.

He later pounced and forced them to reveal their bank details and after killing them texted wife Bibi Patel, 34, and their lodger Mussa Jackson, 40, to say the 'prey are in hellfire'.

Italian born Del Vecchio told wife Patel, the daughter of a Muslim cleric, and Malawian lodger and Muslim convert Jackson to meet him in the Saunders's stolen Toyota Land Cruiser.

Durban High Court heard how by then Rod and Rachel Saunders were dead in the back of it.

Post mortems revealed that Rachel had been hacked a number of times to the back of her skull with a machete like heavy blade and stabbed repeatedly in the upper back.

She had also been brutally battered with a heavy blunt instrument that was believed to be the same murder weapon responsible for caving in the skull of tragic husband Rod.

Both victims were then cocooned in their sleeping bags and thrown in the back of their Toyota Land Cruiser 4 x 4 and driven to rendezvous with the wife and lodger in the forest.

They drove to the Tugela River Bridge and the trio tossed the victims in their blood soaked sleeping bags to the maneaters below but their savaged bodies were found washed up.

Their remains were in such a terrible state due to the injuries they suffered in the violent attack and from predation from wild animals and decomposition that they were unrecognisable.

It took two pathologists using DNA and a dental expert to be able to finally identify them.

The brutal murder of the British couple who traveled the world lecturing on South African flora and fauna shocked the nation but it was another 8 years until they were finally convicted.

The court heard the trio were caught by their greed having gone on a R734,000 (£37,000) spending spree with Dr Rachel Saunder's gold credit card over a two-day period.

They also bought Bitcoin and siphoned the Saunder's savings into their own bank account.

A suspicious shop assistant watching them buying wildly finally challenged the trio for proof one of them was Dr Saunders and the gang fled the store and police were alerted.

Officers were already searching for the much-loved pair unaware they had met such a grisly fate after work colleagues had alerted them when the pair did not keep regular check ins.

Following the trail of credit card spending finally led them to the gang who were found to be already on a terrorist warning list and the Saunders phones were found at their home.

The elite South African police squad the Hawks also found their jewellery and personal belongings and stolen camping equipment and laptops and finally the stolen Toyota.

Inside the 4 x 4 they found heavy blood stains which were linked to Rod and Rachel.

The court heard the couple who ran Summerhill Seeds in Cape Town regularly drove up into the wilds of South Africa in the remote north east to find seeds from rare gladioli flowers.

They collected them and sold them world wide by mail-order from their garden centre company.

Judge Esther Steyn yesterday found all three guilty of double murder, kidnap, robbery and theft after one collapsed trial and a mammoth 160 court days which heard 60 witnesses.

Judge Steyn said DNA evidence and cellphone date and phone usage had linked all three 'without doubt' to the murders which were carried out with 'joint purpose and equal guilt'.

All 3 had refused to leave the police holding cells at the court to hear the verdicts.

The court had earlier heard the couple left Cape Town on February 5, 2018, and driven 900 miles north to meet a visiting BBC wildlife documentary team led by presenter Nick Bailey.

He had posted a photo of the trio together on his Instagram in the Drakensberg Mountains in Kwa-Zulu Natal province where the couple were the stars of a BBC 2 documentary.

He introduced them as 'world-renowned botanists who had been searching for gladioli seeds for over 50 years' and praise their 'incredible knowledge' of the flora of South Africa.

Posting a selfie with last ever photo of the couple he wrote: 'These guys know their South African native plants and vitally where to find them. They sell an incredible range of wild seeds online'.

After parting the Saunders drove off to the remote Ngoye Forest National Park 90 miles north of Durban to seek out their elusive gladioli seeds and unwittingly a date for death..

They had spent two days climbing mountains looking for gladioli as they moved around the dam and were last seen alive at an area near Vryheid on February 9 by witnesses.

The court heard gang ringleader Del Vecchio, 44, had also seen the elderly couple who he had identified as a 'good hunt in the forest' when he alerted his wife and lodger.

He used WhatsApp to contact them on February 9 to say he had a 'target' in the Ngoye National Park.

On February 10 Del Vecchio messaged again that he now 'had the target' and said his 'prey are in hellfire' and told them to drive out from the house to meet him in their stolen Toyota 4 x4.

Del Vecchio texted to them: 'Kill the kuffar (non believers). When the brothers go out and do this work it is very important that the bodies of the victims are never found'.

Jackson later confessed that when they went to the rendezvous the bodies of Rod and Rachel Saunders were wrapped up inside their sleeping bags and they threw them in the river.

He later denied the confession saying it was forced out of him by police.

Prosecutor Mr Mahen Naidu said: 'It is alleged between February 10 and 15, 2018, in the Ngoye Forest the accused did intentionally and unlawfully kill Rodney Saunders and Rachel Saunders'

The exact murder spot was believed to be between eShowe and Mthunzini.

They were all further charged with kidnap, robbery and theft but the trio pleaded not guilty and refused to give evidence from the witness box but were all found guilty yesterday

The Hawks police team raided the home of the accused 18 miles from the murder scene and found an ISIS flag flying in the garden and ISIS pamphlets and literature in the house.

Due to the links to ISIS the Foreign Office put out warnings about a terror threat to British tourists in South Africa after it was revealed Del Vecchio and his wife were on a terrorist watchlist.

No terrorism related charges were brought against the ISIS supporting trio.

Judge Steyn said in finding the trio guilty: 'The state has relied as well on circumstantial evidence but the court is satisfied that the pieces of the puzzle presented fitted together perfectly.

'Bit by bit the evidence formed into a mosaic and the court is satisfied all three acted together in killing the deceased' saying it added to the witness evidence, DNA and phone data.

Sentencing of the three was adjourned until June 19 but in South Africa they will face a mandatory life sentence which is a minimum of 15 years scaling up to a full life sentence.

Speaking by video link to the court a Saunders family spokesman in the UK said: 'Still after so many years the incident itself and the aftermath causes distress to the family.

'It was an awful incident and we do not want to dwell on the event as it was dealt with in detail at the trial'.

Rod married South African born Rachel who has British citizenship in the 1980's when he was a senior manager based at the world-famous Kirstenbosch Botanical Gardens in Cape Town.

Formerly Dr Rachel May she worked nearby as a leading university microbiologist and they quit their jobs to set up Silverhill Seeds working with staff from their home to sell seeds globally.

They also travelled the world lecturing on the flora of South Africa and shortly after their deaths a book on gladioli they were working on was finished by horticultural friends and published to acclaim.
