(CNN) The family of Carla Stefaniak, a woman killed last month at a resort in Costa Rica, has filed a lawsuit in a Florida court against Airbnb and the apartment complex where she stayed.

The complaint alleges Airbnb and Villa le Mas contributed to Florida tourist's death by employing and giving access to all units in the resort to security guard Bismarck Espinosa Martinez, a Nicaraguan immigrant who has been arrested in Stefaniak's death.

The suit also alleges Airbnb and Villa le Mas were negligent because they failed to perform a background check on Martinez, who, the suit says, lacked documentation and legal authorization for employment.

Airbnb said in a statement that it was heartbroken for Stefaniak's family.

"We reached out to provide support to them during this unimaginably difficult time. We have also been in contact with Costa Rican and American law enforcement authorities, and we are standing by to support their investigation, as justice must be served quickly," Airbnb said. "The Villa Le Mas has been removed from the platform."
