A judge set a $250 million bond Thursday for a Michigan woman who is accused of leaving three children alone for years in a house where conditions were so offensive that police evidence technicians wore hazmat suits.

Neighbor says first his son witnessed a killing under his condo. Then came the discovery of 3 kids living alone for years in squalor.

The children's mother, Kelli Bryant, was charged with three counts of first-degree child abuse after the children were discovered living alone in the house on Lydia Lane.
