Bound Bodies Identified As Chicago Dad, Sons

PLEASANT PRAIRIE, Wis. -- Police in Wisconsin have identified three bound bodies that washed up on the shore of Lake Michigan Saturday. They're investigating the case as a homicide.

Kevin Amde, 45, and his two young sons, ages 3 and 6, were reported missing from Chicago in mid-May.

Medical examiners said the amount of time the three were believed to have been in the water is consistent with the date they were reported missing. But they haven't released the cause of death, and said there's no evidence of trauma to any of them.

Authorities said sand-filled plastic bags were tied to the bodies and that sand was put into one child's pants pockets. The sand added 48 pounds of weight.
