Edna Christine Thorne was 15 when she vanished from Philadelphia on June 24, 1975. She left her family home on Front Street to go to a stable at a relative’s house on Tioga Street to see a pony she’d been given for graduation. She was last seen leaving the horse stable wearing a striped shirt and bell-bottom jeans; she was 5 feet 1 inch, about 105 pounds, with brown eyes and naturally brown hair that had been dyed blonde. She took no money or personal belongings except a pack of cigarettes.

Initial speculation that she had run away was questioned because she left virtually nothing behind. Her case was eventually classified as a non-family abduction. Anonymous calls to her older sister claimed knowledge of Edna’s clothing and said she had been buried in Pennypack Park. Family members have accused the brother-in-law who gave her the pony of prior sexual abuse and say he may have been at the stable that day; investigators have considered him a possible suspect.

The Philadelphia Police Department continues to list Edna as missing. If anyone knew Edna, her movements that day, or has information about the stable on Tioga Street, please come forward.
