After a four days search, investigators say there are no signs of human remains at an abandoned cabin in Oswego County.

Those investigators have been looking for possible remains of Heidi Allen, who was kidnapped and disappeared 20 years ago.

New information in the case was uncovered recently which led them to the cabin in the Town of Mexico and reports surfaced earlier this week that the site had been recently disturbed.

Investigators with the State Police, the DA's office and the Onondaga County Medical Examiners Office spent four days at the scene off Rices Road in a wooded area.
