Mohammad Youssef Abdulazeez's uncle is not being detained in Jordan because he is connected to the attack, a family spokesperson, who does not want to be identified, told the Times Free Press.
But Jordanian officials are holding Asaad Ibrahim Asaad Haj Ali so he can be questioned about his contact with his nephew, the spokesperson said.
The Federal Bureau of Investigation has finished interviewing the immediate family. Each member was questioned for many, many hours. Friends have been extensively questioned as well. FBI investigators raided a local apartment complex on Mountain Creek Road on Monday from 6 p.m. to 2 a.m., neighbors told the Times Free Press.
And all of Abdulazeez's electronic communications and personal writings have been reviewed, the spokesperson said.
In that search, officials found that he had sympathized with an Al Quaeda leader named Anwar al-Awlaki, an American al Qaeda leader who has been linked to other U.S. attacks, including the attacks on Fort Hood. Al-Awlaki was killed in a drone attack in 2011.
The family spokesperson said Abdulazeez wrote about the Al Qaeda leader when he was fired from his job in Ohio after failing a drug test. FBI officials have found that he like Al-Awlaki on his Twitter account as well.
"He wrote that he had some affinity for his views," the spokesperson said.
As of now, there has been no link found connecting Abdulazeez to ISIS or any proof that he was working with others to executive the attack in Chattanooga, which killed five military service members and injured several others.
"There is no evidence that he was radicalized by external forces," the spokesperson said. "He certainly appears to have been radicalized by himself."
