Investigators say a family member called 911 on Sunday morning to report the incident at Belair Tower, which is designated as public housing for the elderly in Brockton, Massachusetts.

The 9-year-old boy was staying with his grandmother when he fell from the ninth-floor window onto a concrete walkway.

When first responders arrived, the 9-year-old was unresponsive. He was rushed to the hospital with critical injuries, but efforts to save him were unsuccessful.

People who witnessed the aftermath expressed shock.

"It was a tragedy. Yes, it was," said resident Barbara Leslie. "I was out on the balcony. I had seen the firefighters and the paramedics coming up… to get him up off the ground."

Police were investigating the case, looking for any clues as to how the boy got out of the window. Foul play is not suspected, according to the district attorney’s office.
