The outburst Thursday suggested reality may be settling in for Peterson, who for years casually dismissed suggestions he killed Kathleen Savio in 2004, or that he was behind the 2007 disappearance of his fourth wife, Stacy Peterson.
Savio's death was initially ruled an accident. But after Stacy Peterson disappeared, authorities took another look and reclassified Savio's death as a homicide.
But the sentencing isn't the end. Prosecutors say they could charge Peterson in the disappearance of his fourth wife. And defense attorneys believe the conviction could get tossed because prosecutors heavily relied on hearsay.
