A Connecticut woman has been arrested after police say she held her stepson captive for over two decades, subjecting him to extreme neglect and abuse before he allegedly set fire to their home in a desperate bid for freedom.

A Waterbury woman is accused of holding her stepson captive for 20 years and providing little water and little food. The man, who is now 32, weighed only 68 pounds when he escaped by setting fire to the house, according to officials. The investigation started last month. The state prosecutor called the case “something out of a horror movie.”
