Yesterday afternoon, a 16-year-old boy who had apparently been playing in an abandoned hospital building on Staten Island died after falling down an elevator shaft.

According to police, officers responded to a 911 call at 4:40 p.m. about an incident at 100 Castleton Avenue. They found Marcos Castillo with head trauma, and he was taken to Richmond University Medical Center where he was pronounced dead. It's believed he fell seven stories.

Residents told 1010 WINS that kids were known to hang out at the building, "The kids are in here all the time; they hang out, they party and everything in there. They need security here 24 hours, not just one guy."

The Staten Island Advance reports, "The site was the location of the borough's first volunteer hospital, which was built in 1899. Originally named the Samuel R. Smith Infirmary, it was later renamed Staten Island Hospital and expanded with additional structures. When the hospital moved to Seaview Avenue in Ocean Breeze in the 1970s, the 17-acre property fell into disrepair... According to Advance records, there's a pending judgment of foreclosure on the property, which has accumulated millions of dollars in liens. Once those are foreclosed, the property will be sold."
