 HEARTBREAKING footage shows murdered British teacher Emma Kelty saying "she can't wait" to start her fateful kayaking trip through the Brazilian Amazon. Emma Kelty, who was killed in the Amazon, was mistakenly thought to have been murdered two weeks before her death 
 
 The adventurer was kayaking alone in Brazil. Just a few days before her death, she wrote on Twitter about the dangers of the area she was entering: "So in or near Coari (100km away) I will have my boat stolen and I will be killed too. "But, she was determined to do everything by her own strength and didn't want to use the raft on some places that were difficult to pass. While her body has not yet been found, an Amazonian pirate arrested for her murder has admitted to slitting her throat and throwing her bullet-riddled body into a river.

 Lead investigator Jose Afonso Barradas said the men tried to sell her possessions and "were heard boasting about having a lot of money and gold". Her kayak was found by police, who have recovered some of her stolen belongings - one phone, one credit card, and one GPS system.
– More details are emerging about the murder of British adventurer Emma Kelty during her trip along the Amazon in Brazil, and they're of the worst kind. But police also revealed that her killers made a dumb move that alerted authorities to the crime, reports the Telegraph. Police initially believed that Kelty herself sent out a distress signal from her GPS device, but now they say one of the bandits involved in her death accidentally pressed the button while trying to figure out how to work the device. "Stupid," says a local police official. The signal led police to a riverside village, and they were eventually able to arrest three suspects. Three more are at large, and a seventh man was shot to death, reportedly by a rival gang out to steal Kelty's gear from him. A local resident says the gang member provided details of the crime before his death. It seems that the bandits came across Kelty's remote campsite and incorrectly assumed she was a drug trafficker. "When the men saw her tent they thought it belonged to a Colombian with drugs, so they started firing from about 50 meters away," the resident tells the Telegraph. He says Kelty was hit in the arm and began screaming for help, and the bandits then moved in. According to the resident's account, the men cut off her hair, demanding to know where the drugs were, then sexually abused her, cut her throat, and dumped her body in the river. Authorities have found Kelty's kayak but not her body. The 43-year-old former school headmistress was about 40 days into a 4,000-mile trip, notes the BBC, and she planned to be on the river five or six months. The Sun has a video of Kelty getting ready to embark on the trip. "I can't wait," she says, smiling.
