Police in Costa Rica said the murder of a Miami woman found dead this week outside the Airbnb she was staying at was sexually motivated.
Director of the country’s Judicial Investigation Department, Walter Espinoza, said at a press conference Wednesday his team believes the motive behind the killing of Carla Stefaniak, 36, was ‘sexual’.
Security guard Bismark Espinosa Martinez, 32, was arrested Tuesday in connection with her mysterious death. The victim’s body was found half naked and covered in plastic bags in the back of the San Jose property Monday.
Stefaniak told a friend in a FaceTime call last Tuesday – when she vanished – that she was planning to meet up with the guard to ask him to purchase water because it was storming badly.
That was the last the friend heard from her before her phone battery died around 9pm.
Stefaniak also told her sister-in-law in a text the Airbnb was ‘pretty sketchy’. She said it was raining and the power was going out.
Police in Costa Rica said the murder of Miami woman Carla Stefaniak found dead this week near the Airbnb she rented out was sexually motivated. Security guard Bismark Espinosa Martinez, 32, was arrested Tuesday in connection with her death.

The missing woman’s father identified her body late Tuesday. Stefaniak’s tearful dad Carlos confirmed the identity after the body was found Monday, a day after she vanished last Tuesday.
A posting on the ‘Finding Carla’ Facebook page set up by her family said Costa Rican authorities had finally allowed her father to view her body.
‘Words cannot express the devastation within her family and friends. We want the world to know that we will never forget Carla,’ the tribute post read.
‘We will never forget the joy she brought into our lives, how much she made us laugh.
‘We will always be with her and we know she will always be with us. May god bless her soul.’

Stefaniak’s body was found on Monday half-buried in plastic at the back of the rental property in San Jose, Costa Rica after she vanished last week

An autopsy found stab wounds on her arms and neck, while the cause of death was determined to be a blow to the head.
Investigators found blood inside the Airbnb where she was staying. Blood is also believed to have been found in his nearby apartment.
Authorities said Martinez had been staying next door to Stefaniak and that he gave contradictory statements during questioning.
Her family have been on the ground in Costa Rica since she vanished and have been helping local authorities. Speaking on behalf of the family, Stefaniak’s father Carlos [left] confirmed late Tuesday that the body was that of his daughter. The grieving dad, wept as he discussed her killing on GMA alongside family friend Greg Zwolinksy

Martinez told Stefaniak’s family that he saw her leaving the Airbnb with her luggage at about 5am on November 28 and getting into an unknown car.
Her family said it didn’t make sense because her flight wasn’t until the afternoon and the airport was only 30 minutes away from where she was staying.
Espinoza said officials had analyzed surveillance video from the apartment complex.
Espinoza said the images in the video also did not align with statements made by the security guard.
