FBI lays out horrifying claims against husband accused of kidnaping his wife in ... trends now

The FBI has laid out horrifying claims against a husband who is accused of kidnaping his wife in Spain before fleeing to Miami. 

David Knezevich was arrested on Saturday on his return to the United States from his home country Serbia in connection with the disappearance of Ana María Knezevich Henao.

She was declared missing on February 5 after she failed to meet a friend to travel from Madrid to Barcelona for a conference.

Her husband has been charged with kidnap and the FBI allege he spray painted security camera lenses outside her apartment on February 2 and left an hour later carrying a suitcase. 

But authorities have given no indication about what has happened to Ana María.

Knezevich flew into Miami last weekend where the FBI and officials from the Spanish National Police arrested him.

Investigators claim there is a video of the 36-year-old business owner buying the same brand of paint and duct tape hours earlier.

They allegedly interviewed a woman who insists Knezevich asked her to translate a text which was sent to his wife's friends after she disappeared. 

His attorney Ken Padowitz has said his client is innocent and was in Serbia on the day his wife disappeared. 

But the FBI claim he rented a Peugeot in Belgrade four days earlier. They added that a Spanish driver reported that his license plates were stolen.

While on the night Ana María went missing, the stolen plate number was recorded by Spanish police. 

Authorities also claim that hours after she disappeared, a Peugeot with the stolen license plates went through a toll in Madrid but the driver could not be identified through the tinted windows. 

When the car was returned by Knezevich five weeks later, the license plates had been changed and the windows had been tinted, according to the rental agency, and the car had been driven almost 4,800 miles. 

Knezevich had been married for 13 years but the couple had been going through a difficult separation when she went missing, according to her friends and family.

An 11-page FBI complaint included allegations from an anonymous Colombian woman who he allegedly met on a dating app last fall. 

He allegedly messaged the woman to ask if she would translate a few English sentences into 'perfect Colombian' Spanish for someone who was writing a screenplay. 

But she said she did not speak English and would have to use an online translator which he said was fine, according to investigators.
