The 5-year-old's body was found early Friday morning across the street from his home in Berne, apparently covered in snow, Albany County Sheriff Craig Apple said.

According to Apple, an Amber Alert was issued for the boy after VanAlstyne told police that two men wearing black ski masks entered the home, pinned her to the floor and took the child at about 1:30 p.m. Thursday. She told police the men drove off in a pickup truck.

Apple told WGY-AM on Friday morning that investigators determined the teen's story was false.

Kenneth White's mother lives elsewhere in upstate New York and his father lives in Massachusetts, Apple said.
