Carr was born in
Belize on 21 December 1979 and was brought up by her mother and stepfather. She was one of four children and grew up in great poverty. She never knew her biological father. After moving to England in 1986, the family settled in
Camberley,
Surrey. Her parents' marriage soon ended following a serious
domestic violence incident in which Carr's mother poured boiling fat over her stepfather. The incident caused the couple to be hospitalised with burns, and Carr's mother was charged with
assault. At school, Carr was initially described as polite and helpful by teachers. Friends said that she was a sociable girl who preferred the company of older boys and that she occasionally showed flashes of aggression. Later, she became much more badly behaved, becoming disruptive and attention-seeking, and she had problems relating to authority. In 1990, her headteacher at Cordwallis Junior School in Camberley contacted
social services over her behaviour. Sharon was briefly put into
foster care, but she returned home after only one month. By the time she started secondary school, her mother had a new partner who already had two daughters. ==Murder of Katie Rackliff==
