As she stands by her backpacks and gear in Queropalco, Peru, she says: 'I can't wait to actually start - to get up to the top and actually start kayaking down.
She is then asked how long her journey is expected to take, replying: 'About five to six months - so, yeah, it's a long time.' The video ends with Ms Kelty waving to a camera with a spectacularly beautiful lake and mountain range behind her.
Mr Contos contacted her brother Piers to break the tragic news, who told friends and started the process of making contact with the British Embassy in Peru. Many thanks for getting in touch.'He said: 'There had been a mix-up in identifying the body.
He told Brazil'S G1 website: 'However, I thought it seemed strange, because Emma's last posts put her a long way from where the body was found.'American Mr Contos, an experienced canoeist himself, decided to send a message to Ms Kelty on her GPS device - and to his and her family's relief she replied.'Let's hope it's not a premonition!! There were three other sports people following in kayaks a little behind Emma and it could have been one of them, but that's not been verified yet.'The news that it was Emma's corpse was wrong.
It comes after it emerged that a man arrested over the murder has admitted to slitting her throat and throwing her bullet-riddled body into a river, police say.
One of the group then slit her throat before all four men 'sexually abused her', the villager said.
But before he died - and just hours after the death of Miss Kelty - the 24-year-old told a local villager what the gang had done, it has been claimed.
One of the men, Artur Gomes da Silva, claimed he tried to decapitate the headteacher with a machete.
Horrific new details of the last moments of Emma Kelty's life were revealed yesterday in a confession made by one of the suspects shortly after the British kayaker's death.
Evanilson Gomes da Costa was found dead after going on the run in the wake of the murder having reportedly been shot by rival drug traffickers.
