A non-profit from Oregon that specializes in finding missing people has come to Westchester to search for a mother and her two children who disappeared in 1977.

Doug Bishop, with United Search Corps, heard about the case of Leslie Guthrie and Julie, 6, and Timmy, 3, who disappeared from Katonah 47 years ago.

"Everything points to in this case it simply being an accident," Bishop said.

Police said on February 5, 1977, Leslie drove away with her two children from her house in Katonah and was never seen again.

Leslie's husband, Tim Guthrie, said he buckled his kids in the backseat and waved goodbye.

"I helped her put the kids in the car and they drove off and that was the last I saw them," he said. "I always think of them and where they are."

Bishop's theory - a theory that law enforcement has also long believed - is that Leslie's car is in one of the many bodies of water in and around Katonah.
