PICTURED: American tourist, 79, who was killed by a five-ton bull elephant on safari in Zambia told her friends it 'was going to be her last big adventure'

This is the American woman killed by an elephant on a safari in Zambia over the weekend. 

Minnesota resident Gail Mattson, 79, died in the attack while travelling with five other tourists on a game drive in the Kafue National Park on Saturday. One more person was seriously injured in the attack.

Mattson's family shared heartbreaking pics taken on the day she was killed, which show her holding a flower inside a safari vehicle. Her loved ones said she was 'living life,' that day, as reported by KSTP. 

She lived between Minnesota and Arizona, and told friends the safari would be 'her last big adventure.' 

Her friend John Longabauth added: 'Because her birthday is in the summer — I think she was going to be 80, and she felt like she would start slowing down. 

'To be honest, I don’t know if she’d slow down or not. But at least you wouldn’t be traveling as far, probably.'

Horrifying footage captured the moment the massive elephant charged at the vehicle the tourists were traveling on. 

The vehicle was attacked and rolled when the enraged five-ton animal, apparently separated from its herd, ran flat out to catch up with the vehicle thought to be travelling 25mph - before the driver abruptly stopped. 

Video shows how a tourist says 'oh my goodness' as the elephant keeps pace with the car, as another says 'oh oh' and a third adds 'it's coming fast' in the last desperate moments before collision.

The game ranger suddenly stops the vehicle before the elephant swings right and attacks the safari truck, prompting speculation from wide shots they had run out of road. The driver calls out 'hey hey hey hey hey' loudly when he realizes it is not a mock charge and the five ton elephant standing 10 foot tall is intent on a deadly attack.

The tourists can be heard panicking and screaming while they continue to film the the deadly encounter as the elephant hooks his three-foot tusks under the bodywork of the truck and flips it onto its side before the recording cuts out.

It is believed the guests on the truck were all Americans and staying at the Lufupa River Camp in the Kafue National Park which is the oldest and second largest safari park in the world.

The tented camp charges £350 per person per night.

Wilderness Chief Executive Officer Keith Vincent confirmed that one American guest aged 80 was killed, another was seriously injured and four other tourists had minor injuries.

Vincent said the seriously injured guest was flown to a private medical facility in South Africa and the four others were treated at a clinic and trauma counselling provided.

He said: 'At around 09h30 on Saturday the six guests were on the game drive when the vehicle was unexpectedly charged by the bull elephant.

'Our guides are all extremely well trained and experienced but sadly the terrain and vegetation was such that the guide's route became blocked.

'He could not move the vehicle out of harm's way quickly enough' adding that the Kafue National Park management immediately gave assistance'.

He said they dispatched a helicopter to the scene and given the nature of the incident, the Police, the Department of National Parks & Wildlife, and other authorities are involved in investigating the matter.

Wilderness is a leading conservation and hospitality company that welcomes guests to many African counties to help conserve iconic wilderness areas.

It currently helps conserve six million acres of land over 8 African countries.

Vincent added: 'This is an extremely tragic event and we extend our deepest condolences to the family of the guest who died.

'We are also, naturally supporting those guests and the guide involved in this distressing incident. The deceased will be repatriated to the USA'

The Kafue National Park is the size of Wales set in 22,000 sq km's and is home to African Big 5 of lion, leopard, elephant, buffalo and rhinoceros.

Elephants kill an estimated 500 people a year in Africa.

In March, a 36-year-old guide at Gondwana Private Game Reserve in South Africa was also killed by an elephant.

Daniel Kandela died after encountering the last elephant in the herd, separated from its group.

A statement issued at the time read: "His untimely passing leaves a void within the Gondwana family, as David was not only a colleague but also a source of warmth and expertise among his peers.

'Our hearts and thoughts remain with David’s family and friends during this immensely difficult time. Gondwana pledges to support all those affected by this tragic incident.'
