Tenn. Movie Attacker Had Rap Sheet, Mental Issues

More details are emerging about the man killed Wednesday at a movie theater in Nashville, Tennessee.

Police say 29-year-old Vincente Montano walked into the Antioch theater around 1:00 p.m. as the audience was watching "Mad Max." He sprayed three people with pepper spray and hurt one man with a hatchet. He had a backpack and the air-soft pistol he carried looked real.

Authorities learned he was from the Nashville area, had a history of arrests and had been committed to mental health facilities four times over the years.

Officers shot and killed him as he raced from the back door of the theater into the parking lot.
    
"We heard screams and a shot," eyewitness Jessica Alarid said. "Then metro police came in and escorted us out."

The bomb squad detonated the suspect's backpack and found it contained a "hoax device."

His motive, however, remains a mystery.
