The investigation into 24-year-old Mohammad Youssef Abdulazeez’s July 16 on two military sites in Chattanooga is focused on two key questions, the FBI agent in charge said Wednesday.

Did anyone help Abdulazeez in the attacks?

And is there anyone else who might launch a similar attack?

“Those are our top two priorities for the investigation,” said Ed Reinhold, special agent in charge.

For 17 days after the attack, FBI agents worked side by side with state, local and other federal investigators in the Hamilton County Emergency Operations Center on Amnicola Highway to find clues to those questions.
