Questions surround the mysterious and tragic death of a 7-year-old Newburgh boy, that is also the subject of several criminal investigations.

Official sources tell News 12 an autopsy report shows the boy was severely malnourished and possibly died from starvation hours before his lifeless body was taken to Montefiore St. Luke's hospital by a caregiver.

The child had leg injuries apparently caused by shackles, according to the source.

However, other investigators say the injuries could have also been caused by tight socks or bed sores.

"It has gotten on the radar of law enforcement," said Newburgh Mayor Torrance Harvey. "They are definitely involved, I don't know why."

Child Protective Services is also looking into the death.

Authorities say other children still live in the same apartment, on Williams Street.

"The child died unnecessarily," said Orange County Executive Steven Neuhaus.
