19-year-old girl born with one arm kidnapped, stabbed, burned, and then thrown off a bridge by friends

A 19-year-old teen in Australia was kidnapped, stabbed, burned, and then thrown off a bridge blindfolded by four of her former friends after she allegedly called one of them a "dog". 19-year-old Kayla Kendrigan was driven to the seven-meter high Windsor Bridge in northwest Sydney before being thrown into the Hawkesbury River. Despite her disability and significant injuries at the time, she would manage to swim to safety and find herself treatment.
The culprits have been identified as 19-year-old mother-of-one Brooke Browne, 22-year-old Matthew Leuthwaite, and a 16-year-old boy and a 17-year-old girl who have not been named because of their juvenile status. According to the Sydney Morning Herald, the four decided to attack Kendrigan while they were on their way to pick her up from a friend's house and then forced her into the boot of a Holden Commodore.
