A landscaper died from his injuries Wednesday after he was working on a tree in a Yorktown backyard and became pinned between two branches.The incident occurred at a home on Wildwood Street. Police say 28-year-old Pablo Tenempaquay, of Mahopac, was cutting a branch off a tree when it swung around and pinned him between the tree and the branch.?He was up in the tree, tied up with ropes. He made a cut. The branch came back around, swung in and it looked like it pinned him between the tree and the large branch,? Lake Mohegan Fire Department Chief George Keesler says. ?Our firefighters cut him down, got him on the ground and the patient was in cardiac arrest,? Keesler says.A helicopter was called in with plans to transport Tenempaquay to Westchester Medical Center, but officials say he was too seriously hurt to fly. Tenempaquay was eventually taken by ambulance to Hudson Valley Hospital in Cortlandt, where he died.
