ATLANTA -- The Fayette County district attorney has confirmed DNA test results are back in the Chris Benoit investigation.

D.A. Scott Ballard said the testing was to determine whether there was DNA evidence indicating any person had been in Benoit's home besides him, his wife, Nancy, and their son at the time of their deaths.

The D.A. said he has not seen detailed results yet but he has been informed they do not change the sheriff's office conclusion that the deaths were the result of a murder-suicide carried out by Chris Benoit.

Because Benoit was a professional wrestler the case attracted national attention.
