Wrestler's death a closed case

The Fayette County Sheriff's Office says it has closed its investigation of the killings at pro wrestler Chris Benoit's suburban Atlanta home. The department says investigators stand by their initial conclusion that Benoit killed his wife and 7-year-old son and then himself last June. A medical examiner was unable to say if steroids played a role in the killings, though suspicions linking Benoir's steroid use have lingered.
