NBC NEWS - Fear and chaos erupted Monday night when 20-year-old Richard Shoop walked into a Paramus, New Jersey mall and opened fire.
Shoop fired six shots, then retreated deep into the mall before taking his own life.
Fortunately, no one else was injured.
Shoop's brother says he had no clue that anything was wrong prior to the shooting.
"This was something none of us saw coming," Kevin Shoop said. "We're not sure exactly what caused him to do this and we're all devastated."
