Len Levitt is a subway worker who was shot to death in the park. Light Bulb Len, as he was known at the tracks, used to change bulbs in the stations and tunnels around town. Esposito and Ryan find maps, high-tech gear and surveillance equipment in the victim’s apartment. He may have been tracking someone with the initials “BHS.”
All that fancy equipment in Len’s place belonged to an insurance actuary named Byron H. Singer, aka “BHS.” Singer told Len that the rare red-tailed hawks were sighted in the park. That’s why bird-watcher Len had the equipment.
Castle realizes that if Len was in the park to verify the sighting of the hawks, he would have been armed with a camera. Actually, Len’s camera is found mounted in a tree. The dozens of bird shots end with a photo of man holding a gun on a young boy. Len witnessed a kidnapping. The abductor shot Len when he saw him in the tree. Now the search is on for the unidentified boy.
Castle notices cleat marks on the socks the kid was wearing in the photo. The team does a search of soccer leagues and identifies the kidnap victim as 12-year-old Tyler Donegal. The boy’s parents are divorced. Tyler’s father, Dean, didn’t take the breakup well. He’s been a no-show at his custodial job for two days. The team tracks Dean to a motel near the airport where kidnappers told him to wait for further instructions. Dean was also told not to contact the police or his son is dead.
