MILLBOURNE, PA (CBS) -- A week-long search for a missing Delaware County woman has ended in tragedy.

State police say a body found in Ridley Creek State Park Saturday has been identified as 44-year-old Teresa Mastracola of Milbourne, who was last seen on surveillance video leaving Delaware County Memorial Hospital, where she worked, on December 2nd.

Investigators say Mastracola's body was found in a wooded section of the park where she was known to hike or ride her bike.

State police say foul play does not appear to be a factor in her death, but the investigation is ongoing.

Authorities say Mastracola's car has still not been recovered.
