Costa Rican authorities find blood in Airbnb where Florida woman vanished

Police in Costa Rica have arrested a security guard in connection to the murder of a Miami woman whose body was found outside the Airbnb she rented out.

Bismark Espinosa Martinez, 32, of Nicaragua, was taken into custody following the slaying of Carla Stefaniak, 36, who vanished from her San Jose vacation rental last Tuesday while celebrating her 36th birthday.

Director of the country's Judicial Investigation Department, Walter Espinoza, said she died from head trauma, had knife wounds over her neck and arms and investigators found blood inside the property.

He added that the suspect was staying next door to Stefaniak and gave contradictory statements during questioning.

On Monday, officials discovered her body in the back of the San Jose rental property, which Stefaniak described in a text message to her sister-in-law as being 'pretty sketchy' last Tuesday night.

Her remains had been partially buried and covered with plastic bags, reported NBC6.

According to the Spanish-language news site crhoy.com, specially trained K9 dogs participating in the search for Stefaniak led police to the body at around noon local time. 

Stefaniak traveled to Costa Rica with her sister-in-law April Burton last week to celebrate her 36th birthday and was due to fly home to Hallandale Beach alone Wednesday, the day after she dropped April off at the airport.

Carla checked into her 1pm flight, but never showed up to the airport the next morning, November 28.

Her family and friends say they had not heard from her since Tuesday at 8pm when she texted her sister-in-law from the Airbnb to say it was raining and the power was going out - a scene she described as 'sketchy'.

Her family have been on the ground in Costa Rica, working with local authorities and questioning witnesses. 

A spokesperson for the family said Carla, who works at a Miami insurance agency, dropped her sister-in-law off at the airport in San Jose on November 27 and returned the rental car.
