Renee LaManna has been missing for 21 years. The 57-year-old, who suffers from dementia, was last seen in Ocean City, New Jersey, in 1994, but authorities may close to catching up with her.

In March, someone may have spotted LaManna near a highway in Asheville, North Carolina, but in the last two weeks she’s been spotted more than six times in Greenville, South Carolina, WYFF reported.

“I have spent 21 years looking for Renee. My parents died looking for Renee,” her sister, Margaret LaManna, told WLOS in a phone interview. Her family believes she might be trying to hitchhike to Florida, although the story has now disappeared from the WLOS website. WGNTV reported that North Carolina's Center for Missing Persons said LaManna has a disorder that causes episodes of amnesia.

At the time of her disappearance, LaManna was studying nuclear medicine technology. She was hospitalized after she was found in “an incoherent state,” according to The Charley Project, which profiles “cold cases” of missing people. LaManna was suffering from an anxiety disorder as well as anorexia at the time.

Anyone who sees LaManna is asked to take photos of her and call the authorities.
