The shooter was crouched down beside a car as the resource officer drove directly by.
It is not explicitly stated whether the shooter entered the building through the open door or through other means.
The shooter fired 100 rounds within the classroom where he massacred 21 innocent people, and he was able to fire for two straight minutes before local law enforcement first entered the school building, only to be fired upon themselves by the shooter.
The police then were forced to pull back and seek cover behind the doors.
Local police were on scene for over an hour before the situation was neutralized and the shooter was killed, with federal agents there for nearly a full hour as well.
