The author of the bestselling memoir “A Child Called ‘It:’ One Child’s Courage to Survive” says allegations of child abuse against Connecticut stepmom Kimberly Sullivan are troubling. 

“That is attempted murder,” Dave Pelzer told Fox News Digital, adding details of the Sullivan case are “beyond sadness.”  

Sullivan, 56, was arrested March 12 in Waterbury, Connecticut, after her 32-year-old stepson set a fire at their house Feb. 27 to escape what authorities said were abusive conditions. He weighed just 68 pounds. 

As chronicled in his book, which has sold millions of copies and spent several years on The New York Times Best Sellers list, Pelzer was physically and emotionally abused by his mother from ages 4 to 12. 

“We are shocked and saddened for the victim and at the unspeakable conditions he endured. The now adult victim has shown incredible strength and resilience during this time of healing, and our hearts go out to him,” the department said in a statement.

The department noted there are no records of visits to the Sullivan home on file because reports of neglect and abuse that are unsubstantiated are expunged from its system after five years.

Pelzer said he hopes a caring family member will support the victim, who will have limited state resources for recovery as an adult. 

Fox News Digital reached out to two of the victim’s sisters and Sullivan’s attorney.
