That said, it’s not known if Nolen’s religion had anything, at all, to do with what happened Thursday.
The FBI and other investigators, of course, could eventually find some sort of link or tie Nolen to others.
But that hasn’t happened yet. As of Friday, all U.S. law enforcement officials said was that there are no indications linking the Moore attack to terrorism.
Nolen had been incarcerated until March 2013, for possession of a controlled substance, escaping confinement and resisting an officer.
And he had been trying to convert co-workers to Islam.
Lewis also said there may be other information about Nolen’s past, that he could not reveal, that might help explain the incident, and that the FBI had been called in to dig deeper into Nolen’s background.
“Once we started investigating this initially, and started finding some of the things that he had been involved in, some of the things that he had been saying, we immediately contacted the FBI and got them involved,” Lewis told CNN’s Erin Burnett.
