A Mexican woman has been living at the Cancun, Mexico airport for more than a week for no known reason.
Marcela Silvia Montano Mancera, 45, has been seen in the airport since June 30 and has been using the restrooms to wash up.
Police say she is a Mexican citizen and is not wanted for any crimes.
"She looks like a regular passenger at first glance, people don't look at her, but we have seen her every day…we are not doctors, but it's obvious that she has problems, some of my co-workers tried to speak with her, but at times it seems as if she loses it," an airline worker said.
She has a valid Mexican passport and has been seen sleeping and dining at the airport.
Police have tried to get in touch with her family but have not been able to. They are continuing to keep an eye on her.
