Michael Blagg took the stand Tuesday, something he didn't do during his first trial. He told jurors in Golden that he came home from work in November 2001 and found a blood-soaked mattress in the couple's bedroom.
He called 911 to report his wife Jennifer and daughter Abby missing but said on cross-examination that he didn't search for them in the house first.
Jennifer Blagg's body was found in a landfill but Abby was never found.
Blagg was found guilty of murder in 2004 in Mesa County but his conviction was later overturned because a juror concealed her experience with domestic violence.
