More Info Revealed on ISIS Garland Attacker

Before becoming a law enforcement focus in the attack on a Garland, Texas, cartoon contest, Junaid Hussain went by the cyber pseudonym "TriCk." Tweets between Hussain and one of the gunmen have lent credence to ISIS' claim that it was responsible for the attack, though outside of Hussain's involvement with the terror outfit, it's difficult to say exactly what role ISIS played. What's known of Hussain is pieced together from court records, police documents, online and social media activity, terrorism experts and a fellow hacker. From these sources, the portrait emerges of a dangerous hacker and influential recruiter who's able to crack online banking security systems and who has demonstrated on occasion a zany sense of humor, once dressing up as a Power Ranger and wielding a machine gun during an online chat.
