A St. Joseph County, Michigan couple faces manslaughter and child abuse charges in the disturbing death of a 16-year-old girl.

Anthony and Marsha Springer are the father and adoptive mother of 16-year-old Calista Springer.

Back in February the teen died in a house fire in Centreville.

Police say she was chained to her bed.

A chain and zip ties were around her waist, attached to a bolt on the side of the bed.

Police say Calista was a special needs teen who has tried to escape from the home.

They believe the Springers had been chaining her to the bed because they were tired of getting up every time the alarm went off.

The fire was caused by a faulty vacuum cleaner.

Police say child protective service workers had warned the couple in the past against tethering the teen in case of a fire.

Anthony and Marsha Springer will be arraigned on December 15th.
