NASHUA, N.H. (AP) – The attorney general’s office said Monday the death of a 6-month-old infant last June has been ruled a homicide but no arrest has been made.

Officials said Devin Logan was found unconscious June 19 at the home of Richard and Bernadette Peters in Nashua. He was taken to Southern New Hampshire Medical Center and later to Children’s Hospital in Boston, where he was pronounced dead two days later.

Assistant Attorney General Karen Huntress said an autopsy determined the death was a “homicide, and the cause of his death to be child abuse syndrome with acute head and spinal injuries.”

The Nashua Police Department continues to investigate the death.
