Video shows killer's denials in Ga. girl's slaying

CANTON, Ga. (AP) -- A maintenance man who eventually admitted to sexually assaulting and killing a 7-year-old Georgia girl repeatedly denied any involvement with the crimes during his interrogation.

Video of a polygraph test and interview of 20-year-old Ryan Brunn, conducted five days after Jorelys Rivera disappeared, became a turning point in the investigation.

In the video, first obtained by WXIA-TV, Brunn appears nervous, pulling at his clothes and coughing as if to clear his throat. At one point, he admits that he had lied to a detective about whether he'd run a trash compactor where the child's body was found.

Brunn just began a life sentence for molesting and killing the girl at her Canton apartment complex when he used his sweat shirt to hang himself in his prison cell on Jan. 19.
