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.
Investigators said she died from head trauma and showed evidence she was attacked with a knife.
The suspect allegedly was staying next door to Stefaniak and gave contradictory statements during questioning.
On Monday, officials discovered her body in the back of the rental property, which Stefaniak described in a text message to her sister-in-law as being ‘pretty sketchy’ last Tuesday night.

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.
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.
That’s when she texted her sister-in-law from the Airbnb to say it was raining and the power was going out.
Members of 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.

She then took an Uber to an Airbnb about 30 minutes from the airport. It was the same Uber that drove Carla sightseeing and shopping for the afternoon.
According to family spokesperson Katie Gardner, Carla texted her brother’s wife updates and photos throughout the afternoon until she got back to the Airbnb.
‘Last time we heard from her was 11/27 around 8pm when she said it was raining crazy and power went out,’ April said in an Instagram post in a desperate plea to find her sister-in-law.
‘She continued with ”It’s pretty sketchy here,”’ April said.
April then said she texted Carla to wish her a happy birthday at midnight but received no response.
The next day, April got a call from Carla’s friends saying they had wished her a happy birthday but also got no response.
That’s when they discovered Carla had never boarded her flight back home.

‘She never got back online to check all these birthday wishes,’ he said. ‘This is one more thing telling us that she was abducted.’
The Stefaniak family said they spoke to the Uber driver, Airbnb host and security guards who all say they saw Carla leaving the Airbnb with her luggage around 5am and getting into an unknown car.
