I'm with you on this. Were they actual friends, or friends like Britanee Drexel's "friends" that she went to Myrtle Beach with all those years ago and never returned?
JVM picked up on the weirdness with the two "friends" too:
"MURPHY: . . . What I want to know is, who are those two people he was with in the apartment and why were they missing when the family showed up to look for him? Where are they? I read a report who said it was two women. Who are they? What do they know? The phone is important, but the last people to see him alive are important, too, and they appear to be missing.
VELEZ-MITCHELL: Well, Mark Burnett, you`re the father of Ian, who`s missing. What do you know about these these people? Are they females? And have they cooperated, or have they vanished?
BURNETT: Yes. And we do know where they are, and the NYPD is in contact with these two people and trying to find out some information from them.
VELEZ-MITCHELL: Are they females?
BURNETT: Yes.
VELEZ-MITCHELL: And what was the relationship between your son and these women?
BURNETT: They one of them went to school with Ian at VCU. They were acquaintances; it was not a romantic relationship.
. . .
VELEZ-MITCHELL: Megan King, you`re a friend of Ian`s. Did you know these two women?
KING: No, I didn`t.
VELEZ-MITCHELL: Do you think it`s odd that he goes and shares a place with these two women? Do you think I mean, I don`t know whether they`ve disappeared. Apparently, police are in contact with them, but why wouldn`t they be out here, you know, hollering at the top of their lungs, Our friend is missing! Help us?
KING: Your guess is as good as mine. I know that`s exactly what I would be doing. But honestly I have no idea."
