State records show the killing of a 13-year-old Ruskin girl ended years of abuse.
A sex offender is charged with killing Sarah Lunde by choking her and dumping her body in a pond.
The state Department of Children and Families has released more than one-thousand pages of records detailing a custody battle between Sarah's parents, their violent pasts and investigations involving the suspect.
Sarah had been beaten with a belt buckle and endured punishment that included being left outside, going hungry and being left home alone for long periods. Abuse reports covering Sarah, her four siblings and their mother begin in 1992 and end in 2000.
Records on suspect David Onstott show that he gave his girlfriend's 16-year-old daughter a black eye three years ago. The girl told investigators it was an accident when she was goofing around with Onstott.
