Finally, good riddance and rot in hell.
Evil, evil man.
I have listened to podcasts with single episodes about Alcala & while I cannot recall specifically which ones, here is one by Wondery with a series of episodes about him - anything by them is usually pretty good:

Description
In 1978, Rodney Alcala won a date on the popular TV show, The Dating Game. What no one knew was that he was a prolific serial killer in the middle of a cross-country murder spree. In this six-part series, co-hosts Tracy Pattin (Hollywood & Crime) and Stephen Lang (Avatar, Don’t Breathe) take listeners on an unbelievable journey into Alcala’s twisting secret life. He hid behind normal jobs as a typesetter at a prominent newspaper and a summer camp counselor. How did this predatory monster fool employers, prison psychiatrists, and parole boards — all while committing heinous crimes from coast to coast? And how did a one-time appearance as a game show contestant help lead to his capture? From the makers of Dirty John, Dr. Death, and Young Charlie, learn the story of the most famous serial killer you’ve never heard of - The Dating Game Killer.
