well, about the serial killers, what define them is that they usually kill people more than three times  keeping the same patterns, like the method of killing, choice of people, sequence of actions, and also the interval, so they would not be a serial killer if they killed everyone in the same night, they would just be plain mass murderers. Like that guy who shot everyone in a cinema session, he was a mass murderer, not a serial killer.
