I think that there might be friends/acquaintances of Jessica's who participate on
Find Jessica Heeringa Facebook , but other than the friend who was interviewed on JVM, I'm not aware of a friend coming forward to speak about her.

CHRISTIAN VANANTWERPEN, FRIEND OF JESSICA HEERINGA (via phone): Well, I was just getting gas after work, and Jessica was out taking care of the receipt papers at the pumps. And somebody just started having a conversation with her at the pumps while still in the vehicle, and it was a silver minivan. And I thought that was kind of strange, because he didn`t wait to go inside. He just decided to have a conversation with her on the spot.
VELEZ-MITCHELL: So lay it out for us. Because she`s working alone at this convenience store connected to this gas station. She`s a beautiful young woman, and she is at the pumps. And this guy pulls up in this -- in this silver minivan. Was -- tell us a little bit more.
VANANTWERPEN: Well, he never got out of the vehicle, and he was a couple of bays over. So unfortunately, I didn`t get a really good clean shot of him, but it was just very peculiar to me when the cops came the next day and said that they were looking for a silver minivan. Then I remembered this connection, because it seemed out of place that he was just striking up conversation, never left his vehicle. He didn`t buy gas. He was just there to talk to her at the pumps, almost like he was waiting for her to come outside or something.
VELEZ-MITCHELL: Did you get a sense that Jessica knew him?
VANANTWERPEN: It seemed like it was somebody who had been in there before, that she might have known. He seemed pretty comfortable talking to her. She obviously was dealing with the receipt papers at the time. So she seemed preoccupied and maybe a little annoyed, as well, that somebody was doing this.
And I was driving away so I didn`t think too much of the situation. But it seemed that -- it rang a bell in my mind that something was going on. That didn`t seem quite right...
