According to Costa Rica's El Organismo de Investigación Judicial (or Judicial Investigation Department) search dogs found the partially decomposed body of a woman on Monday - almost a week after Stefaniak's family reported her missing on November 28.
In a Spanish-language press conference later that day, Judicial Investigation Department General Director Walter Espinoza said his team is still working to match the body's fingerprints to Stefaniak's, but said "everything indicates that it is the victim".
A Facebook page set up by friends of the missing woman, Carla Stefaniak, said family members went to the morgue in San Jose on Tuesday to identify the body, but were turned away by local authorities.
Her sister-in-law, April Burton, said she last heard from Stefaniak around 8 p.m. last Tuesday.
A dead body found in Costa Rica was identified on Tuesday as a missing Florida woman, a report said.
Police discovered what appeared to be blood in the apartment where Stefaniak stayed in the San Antonio de Escazu neighborhood, and analyzed surveillance video from the apartment complex. Stefaniak's brother flew to Costa Rica last Friday to search for her. Family members said she missed her flight return flight home to Florida on November 28.
Autopsy results showed Stefaniak died from injuries to the "neck, head and extremities", and also indicated she was injured by some type of weapon, Espinosa said.
After getting dropped off at the Airbnb, Stefaniak went to her room to change and get ready.
They said she had traveled there to celebrate her 36th birthday. He has been living in Costa Rica since June.
Both Caicedo and his wife, who had been traveling with Stefaniak, are skeptical she would leave that early because her flight wasn't scheduled until more than eight hours later.
Her father told reporters in Costa Rica that he does not think the body is his daughter. She continued with, "it's pretty sketchy here", according to Burton. "And then she left", he said. The two texted each other throughout the day Wednesday, Burton said, until Stefaniak suddenly stopped responding to her messages that evening. We strive to keep you up to date about everything that's been happening in Costa Rica.
The investigation remains ongoing. Stefaniak had also checked into the flight, Jaime said, which she always did.
"[She said, ] 'I'm just going to ask the guards to buy me a bottle of water, '" Burton told FOX 13 News last week. "We have received over 1,000 guests with wonderful reviews about the property and our service", Federico Jenkins said.
CNN affiliate WFTS reported that a lawyer for the place where Stefaniak was staying said the facility is temporarily closed. The owners are fully cooperating with the authorities in the investigation and we hope that once the facts are determined, the perpetrator is brought to justice.
