STATEN ISLAND, N.Y. -- Police are investigating after a body was found hanging from a tree in the woods near a church in Great Kills, a police source said.

A man in his 40s was found dead at 10:45 Monday morning in Jack's Pond Bluebelt, the source said, a wooded area between Cleveland Avenue and Hillside Terrace that's bordered by residential homes and Christ Lutheran Church.

Cops currently have a portion of the woods along Hillside Terrace roped off while detectives investigate.

A neighbor who was out walking his dog said he accidentally walked into the woods where the body was found, but police quickly told him to leave the area.

"You could still see the body hanging with a white sheet covering him," he said, declining to give his name.

"It's a shame, whoever he is," he added.

Officers took the man down around 1:40 p.m.

An NYPD spokeswoman said it was being investigated as a possible suicide.

If that turns out to be true, it would be the second notable suicide or suicide attempt on Staten Island in three days.

On Saturday, authorities were summoned to West Brighton after a man set himself on fire in what investigators believe was a suicide attempt, according to several law enforcement sources with knowledge of the incident.

FDNY responded to a call on the 800 block of Post Avenue at 9:49 a.m. and transported a male with burns to Staten Island University Hospital in Ocean Breeze in serious condition.
