This episode covers the mysterious disappearance of Nikki McCown, her fiancé Bobby Webster's suspicious behavior, and the aftermath of the investigation.

After Nikki vanished, Bobby helped distribute flyers but showed little urgency in searching for her. He contacted her community college for a tuition refund and returned her engagement ring shortly after her disappearance.

Police became suspicious of Bobby when he failed a polygraph test regarding his involvement in Nikki's case. Bobby claimed the questions were misleading, focusing on feelings of responsibility rather than actual knowledge of her disappearance.

A woman named Kim, who dated Bobby after Nikki's disappearance, confronted him about the case. His emotional reaction raised further questions about his involvement.

TLDR

Bobby Webster's suspicious actions after Nikki McCown's disappearance raise questions about his involvement in her case.

Episode

1:25
00:00:02
In the days after Nikki McCown vanished, her fiance didn't exactly act like someone waiting for her to come home.
00:00:09
Bobby Webster helped pass out flyers, but beyond that, there really wasn't a lot of searching he did. Instead, within
00:00:15
days, he contacted Nikki's community college to ask about a tuition refund, almost as if he was sure that she
00:00:22
wouldn't be back. He also returned her engagement ring and canceled their wedding venue when their ceremony was
00:00:27
like weeks out. Now, his explanation at the time was that he just like needed the money. But
00:00:34
like, it's sus, right? I mean, police sure thought so. They asked him to come down and take a polygraph, specifically
00:00:39
asking him if he was responsible for Nikki going missing, and according to investigators, he failed.
00:00:45
Now, Bobby says that's unfair, that he was asked if he felt responsible, not if he like knew what would happen or was
00:00:51
responsible. Well, then there's this. There's this woman named Kim who dated Bobby after
00:00:57
Nikki went missing, like a year later, and she got up the nerve to ask him about the case one day, just like
00:01:01
straight up, "Did you kill Nikki?" Bobby didn't answer, he just cried. Now, you know I always say, like you
00:01:09
never know how you're going to react, how someone else would react, until you yourself are in that situation, and
00:01:15
people do grieve very differently. But do you think that this is grief, or do you think that was maybe something
00:01:22
more?
