Woman, 36, mysteriously vanishes after she was last seen at a Starbucks at Atlanta International Airport - as desperate family search for answers

A 36-year-old bipolar woman mysteriously disappeared after visiting a Starbucks at Atlanta's Hartsfield International Airport - sparking a multi-state manhunt.

Hollie Noelle Seay was last seen on surveillance footage at around 5.50pm on June 20, the LaGrange Police Department said.

In the footage, Seay was seen parking her van and walking into the airport, entering the Starbucks and a CBD store.

Her van was later towed from the airport, when officials determined it was abandoned on the curb.

The search for Seay has since been expanded into adjoining states, with the LaGrange Police Department announcing on Tuesday they have released 'be on the lookout' alerts for Seay to the entire state of Georgia and the Southeast, BEE-TV reports.

She is described as being about five-foot-tall, 138 pounds with green eyes and blonde hair with pink and purple streaks in it. 

Seay's mother said she is bipolar and in a manic state, and is not taking her medication.

In a video posted to her Instagram just two days before she disappeared, Seay could be seen descending stairs and grabbing a bottle of alcohol.

Another video posted on June 17 showed her mouthing Timothee Chalamet's lines in Wonka. 

Photos on Facebook also seem to suggest she has a husband and three children.

Seay's family is now concerned about her wellbeing, with one friend on Facebook writing and 'as someone who has also fought a mental health crisis that ended with me evading being found, I can assure you it is crucial she is found quickly and can receive the help she needs.'
