Has there ever been a case where someone convicted of three or more murders was released from prison?
I asume you mean “in the USA”? I mean, there are many countries in which life sentence isn’t a thing.
Quite a few eventually get released, Wikipedia has a long list of serial killers, just search that list for the word “released”:

I’m gonna share a golden case from italy:
https://en.wikipedia.org/wiki/Giovanni_Brusca
This man who himself declared committed between 100 and 200 murders (he lost track) got released after 25 years and walks free.
Only two convicted murders but one of them was her own sister, Karla Homolka served 12 years and got out in 2005.
Robert Durst killed at least 3 people and completely avoided justice because he was rich, at least until he outed himself on camera. There’s a documentary on Hulu called The Jinx
