generally, a serial killer does multiple individual murderers over an extended period. this contrasts with a mass murderer, who kills a bunch of people in a single event, or a spree killer who does multiple killings over a short time span. a serial killer may take a couple years to kill 5 people while a spree killer does it in a weekend, and a mass killer manages it in a few minutes.
