What exactly prompted Donald Blom to confess to the kidnapping and killing of Katie Poirier is unclear. But after more than two months in prison, Blom gave a statement to authorities yesterday in which he confessed he kidnapped Poirier and said the human remains found on his property are hers. Blom's attorneys discouraged him from making the plea agreement, since he'll still likely face life in prison without parole. But Blom said he wants to get the matter behind him.
