Police are investigating the death of a 21-year-old woman whose body was found Tuesday morning outside her home.

The Ulster County Sheriff''s Office said the woman, identified as Kalie M. Herdman, was discovered about 10:10 a.m. in a dry well at 31 Station Road in Phoenicia, where she lived.

The Sheriff''s Office did not say how Herdman might have died or whether her death is considered suspicious - only that the investigation remains active.

There was no police activity or crime scene tape at the Herdman property Tuesday evening, and a man answering the door at the family home declined to comment.

The Sheriff''s Office said it was assisted by the state police, the town of Shandaken police and the New York City Department of Environmental Protection police.
