(NewsNation) — Florida resident Ana Knezevich has been missing in Spain for over 40 days. Her estranged husband, David, reportedly refused a polygraph test when the FBI offered him one.
Knezevich, a resident of Florida, went missing at the beginning of February. 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 her 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.
It’s unclear where David Knezevich was at the time of the disappearance. According to the husband’s attorney, Ken Padowitz, he was in Serbia when Ana disappeared and has been cooperating with both Spanish police and the FBI.
“He’s spoken to the police a number of times,” Padowitz said during an appearance on “CUOMO.” “I have reached out to the FBI and let them know that we are available to aid in any way. He’s given police information on credit cards, attempted to hire a lawyer in Spain.”
However, Sanna Rameu, Ana’s best friend, says David was at the couple’s Fort Lauderdale home, not in Serbia, when Ana disappeared.
Madrid police have said that the investigation is ongoing, but have yet to release further details.
