A criminal complaint filed Thursday against Enrique Marquez marked the first charges — and the first arrest — produced by the sprawling investigation into the Dec. 2 attack in San Bernardino, Calif.
While the complaint was largely focused on Marquez’s statements and the allegations against him, the 36-page affidavit filled out by an FBI agent also offers the most insight available yet into Syed Rizwan Farook, who authorities say went with his wife to a holiday gathering and killed 14 people.
The complaint is full of new details about Farook’s background and influences, information that the FBI learned from a series of interviews with the 24-year-old Marquez.
The document paints a picture of Farook, 28, as a young man who spent years steeped in extremist thought easily accessible online. He is described as hoping to travel to join a terrorist group and, with Marquez, plotting to carry out attacks here.
