A police spokesman said Vincente David Montano, the homeless man who attacked people at a movie theater in Nashville, Tennessee had a canister of propane, lighter fluid and a lighter and may have intended on setting off an explosive device.

Don Aaron, Metro Nashville Police spokesman, said Thursday the attacker made a gash on the canister of propane, rending it useless.

Aaron said Vincente David Montano started his attack by pepper-spraying two women who were sitting in the theater. A man who was with them intervened and he was wounded by an ax that Montano was carrying. Montano also had a pellet gun. He was killed by police.

What initially appeared to be another mass shooting at a movie theater is beginning to look more like the last desperate act of a severely disturbed homeless man who may have had no intention of harming large numbers of people — but perhaps knew he himself could be killed.

Police say the 29-year-old man identified as Vincente David Montano bought a ticket for “Mad Max: Fury Road” in southern Nashville and entered with pepper spray, a pellet gun and an ax. He fired the pepper spray at several people in the audience before a police officer summoned by other theatergoers confronted him. Montano was shot dead by a SWAT team as he tried to escape out of a back door.

Metro Nashville Police spokesman Don Aaron says Montano had been treated at least four times for psychiatric issues.
