I don’t immediately know what in particular transitions someone from killer to “serial” killer.
But I could see if it was someone who wiped out a van of people or a husband coming back home to his wife cheating with a couple and murdering them being potentially released after a long sentence.
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.
