Details of Disappearance
Edna was last seen in Philadelphia, Pennsylvania on June 24,1975. She had recently graduated from Stetson Junior High School, and her brother-in-law gave her a pony as a gift. The day of her disappearance, Edna left her family's home on Front Street to go visit her new horse at its stable on a relative's home at Tioga Street. Edna invited her thirteen-year-old sister to join her, but her sister stayed behind. Edna was last seen leaving the Tioga Street stable. She has never been heard from again.
Although Edna had been in foster care as a child and she had recently argued with her sister, there is no indication she'd been planning to run from home and she didn't take any money with her, only a pack of cigarettes. She wasn't dating anyone at the time of her disappearance. After she went missing, her older sister got disturbing phone calls from a man who claimed he knew what Edna was wearing when she disappeared and claimed he'd buried her in Pennypack Park. Investigators believe she was abducted by a non-family member and may have been killed, but little information is available in her case.
