A US teen and self-described "werewolf" has admitted decapitating a dog and posting a photo of its mutilated body online.
Sarah Rodriguez, who goes by the name "Wolfie", is being investigated by police after the offensive picture caused widespread outrage online.
A woman in the teen’s town of San Antonio, Texas saw the photo and told police she believed her dog — which had been missing since January 2 — was the one in the picture.
Rodriguez said the dog was killed after being hit by a car and was already dead before she obtained it.
She said the dog was named Shadow and was owned by her friend, KENS-TV reports.
Rodriguez also told reporters she thinks she is a dog, and would never hurt another dog.
The 18-year-old has Tourette's Syndrome and suffered a head injury in a car accident when she was eight years old.
Her police record shows she has been charged with burglary and was once arrested at a high school for carrying a large knife on campus.
Rodriguez is also the subject of a separate investigation over claims her pet dogs live in unsanitary conditions.
