In August 1996, 33-year-old Marcia Ryan spontaneously decided to drive 20 hours to her parents’ vacation home in Queensland, northeastern Australia. This was out of character for her, and the decision came after a short period of paranoid behavior.
Marcia never made it to her parents’ place. She and her dog Ziggy mysteriously disappeared, leaving behind her car and wallet. Now, three decades later, police still don’t know what happened to Marcia. However, they have reopened the case and found new evidence in recent years.
Marcia Ryan was born on July 19, 1963, in Australia. Her friends and family described her as smart, honest, dependable, and reliable. She enjoyed the outdoors and participated in activities like scuba diving.
She struggled with substance abuse and was in a toxic relationship in her early twenties. She spent some time in a rehab facility and eventually recovered. Afterward, she seemed to be thriving and started working for her aunt and uncle’s transport company.
By 1996, Marcia was a homeowner in Seaford, Victoria, and had a 10-year-old dog named Ziggy, who was as loyal as could be. In August, she took in a boarder named Steven but kicked him out within days.
Years later, Steven claimed in an interview that they had gotten along well, and he had lived there for a month.
Marcia began to display signs of paranoia about Steven. She apparently saw him leave bones and feathers in the backyard, and she was afraid that he was going to place a curse or spell on her. Her loved ones became concerned, especially since she had never talked like this before.
On August 19, she told her manager that she wasn’t feeling well and needed to go home. She left at 12:30 p.m. It was also the same day that Steven was moving out. Her brother, Mark, was there to ensure everything went smoothly. He stayed with his sister until 10:40 p.m.
Marcia called her parents about 15 minutes after her brother left. They were at their vacation home in Surfer’s Paradise, Queensland.

She planned to drive there and stay with them for a few weeks. By the time she made the phone call, she had already left the house. Her parents were surprised by her impulsivity.
Early into her road trip, she made a 45-minute detour to withdraw $50 from an ATM in Camberwell. Then, she ran out of gas and pulled over near a gas station in an inland town called Yallourn.
A truck driver spotted Marcia walking on the side of the highway at 11:50 p.m. She seemed distressed and ignored his offer for a ride. It was the last time anyone saw her.
A police car caught sight of her vehicle at 2:48 a.m. No one was in or around the car. When Marcia’s family didn’t hear from her for three days, they began to worry.
Her other brother, Tony, went to her home to check out the place. The police had called to inform her that her car would be impounded soon, and another caller let her know that they had found her wallet on the highway.
The wallet was likely thrown from the driver’s side window. A large-scale search was launched, and authorities spent weeks searching the area. Sadly, no trace of her was discovered.
Eventually, the coroner ruled that Marcia had died on the day she went missing, even though no evidence of foul play had been found. Her former tenant was ruled out as a suspect early on in the investigation. Her parents died, never knowing what happened to her.
Since reopening the case, the police discovered that the gas gauge in Marcia’s car was broken. Her car likely still had gas in it at the time. The police will continue reviewing the files, and hopefully, a set of fresh eyes can come up with something new.
Anyone who may have information about Marcia’s case is urged to contact Crime Stoppers Australia at 1-800-333-000.
