(NewsNation) — The absence of David Knezevich’s involvement in the search for his estranged wife Ana Maria Knezevich has raised eyebrows, with some questioning why he has not traveled to Spain to assist authorities in the effort.

David’s attorney Ken Padowitz says his client “has not been absent” from the investigation to find Ana. David has been living in Serbia since their separation from Ana.

“He’s spoken to the police a number of times,” Padowitz said during a Monday 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.”

Ana traveled from South Florida to Spain in December to get away for a while, according to her family. She is originally from Colombia and was going through a divorce from her Serbian husband.

While traveling, she vanished — over two weeks ago, shortly after a man wearing a motorcycle helmet disabled the security cameras at her Madrid apartment building by spray painting the lenses.

The next day, friends of Ana’s say they received mysterious text messages from the 40-year-old’s phone. One text was in English and another one was in Spanish, saying she was running off for a few days with a man she had just met.

Brandee Smith, a longtime friend of the Knezevichs, told NewsNation that Ana 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.
