BIRMINGHAM, Ala. - An Alabama teenager pleaded guilty on Tuesday in the death of his 9-year-old half-sister, who was hanged from a tree in their yard, but the motive remains a mystery to prosecutors more than three years later.
Court documents show John Dillon Salers, 18, pleaded guilty to murder in St. Clair County, about 30 miles east of Birmingham, and a judge sentenced him to 20 years in prison.
Salers could be released earlier since he got credit for jail time served and will be eligible for parole. Using uneven print, Salers signed a court document in which he stated no one had coerced him or promised him anything to plead guilty in the death of Katelynn Arnold in May 2012.
Salers was 14 when the girl was found hanging in a tall hardwood outside the rural home they shared with relatives in Ragland, Ala.
Authorities at the time said the girl was outside playing when her aunt realized she was missing. She went out to find the child hanged by a cotton rope that once held a tire swing.
Salers went to bed afterward, and police awoke the youth to question him and place him under arrest. He was initially charged as an adult with capital murder but pleaded guilty to a reduced charge.
