Why were 2 windows blown out?

The second window gave him a line of fire toward the only other exit from the concert venue. By firing from both windows he was able to cut off both escape routes and pin the crowd in the middle where they were easy pickings.

Did the shooter stop shooting, run to the other room and start shooting again?

Why did he stop shooting after 9 minutes? I thought the police took 72 minutes to go into his room.

Could a 2nd person have killed him?
