Amy Ahearn, an English professor at Saddleback College in Orange County, California, who has been missing since August was found alive Friday night.

Amy Ahearn vanished in a suburban city of Los Angeles on August 17th before being located by Los Angeles Police nearly four months later.

Feared of suffering from Huntington’s Disease, which is a delusional disorder, she was being evaluated Friday night.

Amy Ahearn, 40, was reported missing after not showing up for classes on August 22nd.

The professor reappeared temporarily in mid-September when a family saw her outside her home in Norwalk around midnight and were able to coax her to come inside theirs.

Amy Ahearn had told the family that she was out there “waiting for a ride from a friend”, Ana Ruvalcaba, who found her, told the Los Cerritos community news.

Ana Ruvalcaba says they took Amy Ahearn to a local Motel 6 so she could get warm and have a place to stay, but she wondered off to a nearby parking lot and disappeared again until November.

Ana Ruvalcaba said they had called a “Helpline Hotline” for assistance after Amy Ahearn wondered off but were told there was “little they could do” for her.

Hearing the news of Amy Ahearn’s second disappearance, her sister, Marjorie Ahearn who lives near Chicago told LCCN that she was “beyond disbelief”.

“How could this happen?” Amy Ahearn’ sister asked, dumfounded.

Hearing the news of her final reappearance, family said they were “overjoyed” at hearing the news, writing on a missing Facebook page for Amy Ahearn their thanks to investigators hired who “never gave up on her quest to find Amy”.

“I have cognitive and physical limitations due to my HD but [Kathie Allen from Allen Morris Investigations] kept working with me patiently to get the word out about Amy and to locate her,” her sister wrote.

The Community news learned that Amy Ahearn was going through a divorce at the time of her disappearance.
