Terrified voices, video depict Louisiana shooter's rampage

In new video and audio, we heard desperate pleas for more ambulances -- voices recorded in 911 calls from last week's movie theater shootings in Louisiana. The gunman killed two and wounded nine, before taking his life. CBS News has the tapes and new video.

The shooter, John Houser, 59, is seen purchasing a ticket to the movie "Trainwreck" at 7:20 p.m. last Thursday.

A second camera shows him entering the lobby. He walks down a long hallway, pauses, goes left, then turns around and enters theater 14, under the cover of darkness, hiding a 40-caliber handgun.

"We're at The Grand Theater on Johnson Street and someone just started shooting people," said a man on a 911 call.

The first 911 call was made at 7:28 p.m., 19 more would follow.

"He was wearing a white polo, I don't know it was an older man," said one caller.

"One is shot in the leg," said another, who then asked a victim: "You're shot in the leg, too? The ambulance [is] on the way."

Dashcam video shows a Lafayette police officer racing to the scene at 7:33 p.m. -- 12 minutes after a gunman entered the theater.

"Get the ambulances over here now," a detective shouted at emergency responders.

School teachers Jena Meaux and Ali Martin were among the survivors.

"I felt a bullet go through the side of my leg and exit the other side of my leg," said Meaux, speaking publicly Wednesday night for the first time since the shooting. She told a crowd of 3,000 people the gunshots didn't seem real. "As I crawled I was praying because I really thought he was gonna shoot me in the back of the head as I crawled down the rail."

Of the nine victims who were shot, only one remains in the hospital. In Lafayette tonight, thousands of people are expected at what is said to be a community wide healing event.
