New surveillance video obtained by WNBC appears to show the gunman who opened fire inside a New Jersey mall calm and determined as he walked through the building dressed in black and carrying a rifle. CNN's Jason Carroll reports.
A total of five cameras in the Westfield Garden State Plaza mall captured 20-year-old Richard Shoop prowling the mall around closing time on November 4 before he took his own life.
Shoop's brother, Kevin, called authorities after hearing about the shooting and said he thought Shoop might be the gunman, Molinelli said. Police did not confirm the shooter's identity until they found his body.
"We're not sure exactly what caused him to do this, and we're all devastated," Kevin Shoop told reporters.
"My brother intended to harm nobody else but himself. He just, sadly, decided to make ... an act of self-indulgence by taking his own life publicly. And it's a tragedy to us all," he said.
At the time, Eddie Kahmann, who works inside the mall, told CNN he heard 6 or 7 gunshots around 9:20 p.m. ET.
"There was just people running like crazy, so I quickly just closed my doors, ran to the back, turned off all the lights, music and everything, just to stay hidden," he said.
Allie Cozic, another mall employee, said she saw "someone dressed in all black, carrying a large gun, walk past our store."
She said she heard loud bangs about 10 minutes before her store was set to close for the night.
"It was just chaos. Everyone was just kind of running to wherever they could," Cozic said.
