The NY Daily News reported that these 'cages' were cribs with tops that latched down at night and some had alarms to warn the parents if one of the children lifted it. They were painted in bright primary colors (while they have been playing up the 40"x40" deep, they have not said how long they are-40 inches is a bit wider that a standard crib) It also reported statements by neighbors saying the children played frequently in the yard, were clean and well-fed and "better dressed than most kids in Cleveland". It went on to say that a family psychiatrist recommended this sleeping arrangement to keep them from harming each other due to the problems these kids had including autism and fetal alcohol syndrome.
No charges have yet been filed.

My primary concern would be a fire with this arrangement. Not ever having to deal with severe disorders in children, I can't place judgement on this if it was indeed suggested by a professional. Bizarre, yes, but criminal, no idea....
