“Although it is important not to re-victimize a family that loses a child, in this case Detective Leonardo Solo and other members of the Special Victims Unit used their diligence and fought for justice for the child who no longer had a voice in the matter,” Assistant Chief of Investigations Karl Jacobson said.

On March 4, Ratchford, of New Haven, turned himself in. Ratchford was arrested on first-degree manslaughter charges and risk of injury to a child.
