On Wednesday in Tennessee a man with “significant” psychological issues attacked movie goers during a viewing of Mad Max: Fury Road.

He was armed with a hatchet, a pellet gun and pepper spray. First he unleashed a large amount of pepper spray on the audience and was later shot dead by SWAT team members as he tried to escape out of a back door.

The attacker was identified as Vincente David Montano, 29 of Nashville, TN. He was carrying two backpacks, one hanging from his chest. Montano was also wearing a surgical mask to protect himself from the pepper spray.

According to Nashville Police spokesman, Don Aaron, three people were blasted with the pepper spray and eight people were in the theater in total.

Even though police have yet to uncover a motive they said Montano was committed for psychiatric treatment at least four times since 2004.

He was also arrested in TN in 2004 for assault and resisting arrest. On Monday he was reported as a missing person to the Murfreesboro police department.

Police thought he was armed with a gun but it was an airsoft pellet gun. When they first approached him he exchanged fire with the police. Aaron said:

The gun is a very realistic looking gun that strongly resembles a semiautomatic pistol. If someone confronts you with it, you would think it was a real pistol. Obviously an airsoft gun makes noise. When the initial officer who confronted him reported that the gun was aimed at him, the trigger was pulled, that officer heard noises. That’s when the officer fired his weapon at the suspect in that initial confrontation.
