ORIGINAL STORY: Authorities in Costa Rica have located a body in their search for a Florida woman who went missing while on vacation .
A spokesperson for Costa Rica's Judicial Investigation Department confirmed that remains were found.
The body was found in a wooded area Monday as investigators combed through the region where Miami resident and Tampa native, Carla Stefaniak, 36, spent what was supposed to be her final night in Costa Rica last week, Judicial Investigator Director Walter Espinoza said in a press conference. The remains belong to a woman, but they have not yet been positively identified, Espinoza said.
In addition, fluids found in the apartment where Stefaniak was staying have the consistency of blood, Epsinoza said.
Stefaniak traveled to Costa Rica to celebrate her 36th birthday, according to family. She left for Costa Rica on Thanksgiving Day but had not been heard from since Tuesday, her brother, Carlos Caicedo , told ABC Action News.
Stefaniak's sister-in-law, April Burton, accompanied her in Costa Rica, but Burton flew back one day early. Stefaniak and Burton are like "best friends," Caicedo said, adding that his sister talks to his wife more than she talks to him. The pair had planned to stay in beach towns outside of San Jose, Caicdeo said, and they posted photos and video to social media, documenting their trip.
Here is a timeline of the last time Stefaniak's was heard from:

1:04 p.m.: Stefaniak arrived to the Villa Buena Vista in San Jose and took about 30 to 50 minutes to change at the hostel while the driver waited, according to the timeline.
