(NewsNation) — Ana Maria Knezevich, a resident of Florida, has been missing since Feb. 5. She disappeared while visiting Madrid. The disappearance occurred the same night as an unidentified individual was spotted vandalizing security cameras, further complicating the investigation into Knezevich’s disappearance.

Knezevich had traveled to Madrid as part of her efforts to cope with a recent divorce and to gather her thoughts. She had plans to continue her journey to Barcelona with a friend, but she failed to arrive at the designated train station. Concerns escalated when Spanish authorities found no evidence of robbery during a search of her apartment.

Adding to the mystery are text messages purportedly sent from Knezevich’s phone, indicating that she had met someone after therapy and intended to visit his house. However, friends and family members doubt the authenticity of these messages, citing inconsistencies in language and tone that suggest they were not authored by Knezevich herself.

Voice messages obtained by NewsNation’s “CUOMO” team offer insights into Knezevich’s demeanor leading up to her disappearance.

In one message sent a week and a half prior, she is meticulous and detailed, traits that seem incongruent with someone suddenly disappearing without notice.

“Hey, good morning. I woke up, went to the gym, got the apartment ready. I’m gonna buy some like cleaning stuff now. I fixed my hair, my nails and I’m just heading back. How are you? I miss you too. Bye,” she said.

Another message, believed to be from the day she went missing, shows her excitement about plans to visit another apartment and travel to Barcelona with a friend.

“I saw an apartment that I loved. Yes. So hopefully, it will be mine. I am now on my way to see another one. Everything’s doing great. I’m feeling actually really good. I’m going on Monday to Barcelona with a friend of mine. It’s just a day trip. She’s very excited about it,” she said.

Brandee Smith, a longtime friend of Knezevich and her estranged husband, David, said Knezevich is a calm and intelligent person, asserting that the purported text messages do not align with her character. Smith, along with others close to Knezevich, insists that she would have maintained communication with friends, making her sudden silence highly unusual.

“It absolutely feels like a missing persons investigation because she would have messaged her friends, her girlfriends. This is what women do. Women message each other and tell them what’s going on,” Smith said.

The absence of David Knezevich’s involvement in the search has raised eyebrows, with some questioning why he has not traveled to Spain to assist in locating his missing wife.

“I would say certainly think after all of this history that they spent together, that he would go looking for her,” Smith said.

NewsNation’s Brian Entin reached out to Ana’s husband, but he has not replied. Family members believe he is in Serbia.
