BOSTON >> A 3-year-old boy who suffered traumatic injuries at his Boston home last weekend has died.

Police confirm that the boy died Tuesday. He was taken to the hospital Sunday night after he was found unresponsive in his Roxbury home.

Authorities have not released the nature of his injuries or the cause of death. No one has been criminally charged.

A spokeswoman for the state Department of Children and Families says the child welfare agency had an open case with the boy's family. The last time an agency social worker was in touch with the family on Friday, the boy was clean, well-fed and had no reported issues.

The agency is cooperating with law enforcement in the investigation and has taken custody of another child who lived in the home.
