Investigators say the body was discovered in a heavily wooded area of the park, where 44-year-old Teresa Mastracola would often hike and ride her bicycle.

Police have not made an identification of the body, but they say it does not appear that foul play was involved with the death.

Millbourne borough police say Mastracola was last seen on December 2nd entering Delaware County Memorial Hospital, where she works, around 6:30 in the morning. Surveillance video shows her leaving about 10 minutes later.

The investigation is ongoing.
