GARLAND, TX - ISIS is now claiming responsibility for the attack at the Curtis Culwell Center in Garland. In a radio broadcast, the group calls Nadir Soofi and Elton Simpson "brothers" and "soldiers of Al-Khilafah." That's their way of saying ISIS brothers.

ISIS may call them brothers, but Nadir Soofi's grandmother, who lives near Houston, says he's not terrorist.

When asked if he felt like Muslim people were persecuted, his grandmother Shirley Dromgoole responded, "No, I don't think so. Because he wasn't persecuted."

And a former lawyer for Elton Simpson says she never saw anything like this coming.

"I believe that perhaps he might have just snapped when he heard about the cartoon contest," Kristina Sitton said.

It's back to business at the Culwell Center. Garland students are taking AP tests there this week.

But everyone's still on edge. Twitter went nuts when a fire alarm went off next door at Naaman Forest High School.

Turned out to be a false alarm.

Garland PD says the hero cop who shot and killed Soofi and Simpson wants to remain anonymous. Hard to blame him. The ISIS radio broadcast had a chilling message for Americans.

"Future attacks are going to be harsher and worse. The future is just around the corner."
