A young boy playing in his Brooklyn front yard died on Thursday after a concrete planter fell from the facade of the house and hit him. "I saw mom was crying, screaming. She was saying, 'someone call 911'," a neighbor said.

The tragedy unfolded in Marine Park, at 2224 Ryder Street. Police say that officers responded to a 911 call just before 5:30 p.m.: "Upon arrival, responding officers discovered an 8 year-old male unconscious and unresponsive with trauma to the head." An hour later, the NYPD announced that Kevin Reilly had been pronounced dead at Coney Island Hospital.

Police sources told the Daily News that the boy had been climbing on a metal gate covering the windows on the ground floor of the house. He reached up to grab the flower box, which is heavy and made of concrete or ceramic.

The planter then fell on the boy. Another neighbor, Rahadel Kabir, told WABC 7, "What I could see from my attic she was trying to lift that piece, but that's the only view I had. She couldn't really lift it. It turned out two gentlemen ran over before I could get there tried to get there and tried CPR."

The NYPD requested the Department of Buildings to inspect the building.

One shocked neighbor told NBC New York, "Who would have thought a potted plant would be so dangerous? It's awful."
