A man accused of torturing and killing a teenager whose death was once considered accidental was found guilty of murder Friday.

Joseph Clark, 19, became a suspect in the death of 14-year-old Christian Steiner when charged in the torturing of another teenager who said Clark broke bones in his legs and then "fixed" them.Clark was convicted and sentenced to 100 years in that case, and it led investigators to exhume the remains of Steiner, whose decomposed body was found in the Wisconsin River in 1994. The body was draped over a tree with its legs badly broken.

Prosecutors claimed the similarity of Steiner's injuries compared to the 13-year-old teenager who escaped Clark in 1995 after being tortured over two days proved Clark was the killer.
