[Wikipedia] “a serial killer is a person who murders three or more people, in two or more separate events over a period of time, for primarily psychological reasons.
That actually fits, depending upon what you mean by "separate events." I'm sure each person's murder would have appeared to be a "separate event" to the victim.
I doubt he killed them all at the same time.
