A teenage girl who was the subject of an Amber Alert has been charged with murdering a man she lured online.

Natalie Navarro, 17, as well as her boyfriend and apparent accomplice Yordy Martinez, 21, face capital murder charges in the shooting death of 21-year-old Arturo Pena on August 27.

Navarro is also accused of being ‘in the course of committing and attempting’ to rob Pena when she allegedly shot him, according to the indictment earlier this week.

Investigators believe that Navarro met Pena online, said the Garland Police Department

Navarro told cops ‘she had spoken to Yordy once before online but had never met him in person the night of the actual murder,’ police spokesperson Richard Maldonado told Fox News Digital.

However, authorities believe she was not telling the whole truth.

Navarro disappeared from an apartment complex in the Far East Dallas neighborhood and The Dallas Police Department issued an Amber Alert for her on September 1, three days after Pena’s body was discovered.

Natalie Navarro, who was the subject of an Amber Alert, and her boyfriend allegedly murdered Arturo Pena whom she apparently met online.
