Has there ever been a case where someone convicted of three or more murders was released from prison?
Quite a few eventually get released, Wikipedia has a long list of serial killers, just search that list for the word "released":

The only one I could find was Franz Schmidt who killed three people between 1957 and 1983. Was released in 2003 and died in 2013.

at least two of these dudes fit the bill
Only two convicted murders but one of them was her own sister, Karla Homolka served 12 years and got out in 2005.
Her and her husband were sick af. It's good they got caught (relatively) early into their thing, they almost certainly would've continued on with that shit indefinitely if they could've.
Yes. He's never disclosed where the bodies are, so there's never been enough physical evidence for an arrest.
I would add an addendum that they’re 3 separate murders cases and not a single event.
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.
