0:00.0	The
0:07.0	The Today on missing, we are speaking with author Courtney Lund O'Neill who wrote a great book called Postmortem,
0:43.1	What Survives the John Wayne Gacy Murders.
0:45.8	This episode first played on Crawl Space about a month ago.
0:49.3	Lance, what did you think of this conversation?
0:50.5	I think this conversation coming up really scratches an itch that a lot of our
0:54.7	listeners have. We discuss a serial killer that is among the top echelon of serial killer lore,
1:02.0	and we don't really cover those like top-level serial killers often. We don't often cover in-depth

1:50.6	That's another good way to put it.
1:51.7	A true crime memoir because Courtney writes this story about her mom, who was a friend with Rob
1:59.6	Peast.
2:01.1	And Rob Peast went missing and really was abducted and murdered by John Wayne Gasey.
2:07.2	So Courtney Lundoniel's mom, Kim Byers, worked with Rob in this pharmacy in 1978 and was one of the last people to see him alive.
