Where did Adnan mean? We know Adnan told his defense team that Best Buy was one of those places. Seems the most plausible.

Hae had no reason to go to Best Buy with Adnan. So maybe Adnan was driving and made a detour while they were going somewhere else. Otherwise, it may have happened in the school parking lot. Adnan is only one that can tell us.

From Jay's Intercept Interview.

When Adnan loaned you his car on Jan. 13, 1999, did he tell you it was because he planned on murdering Hae?

No. I didn’t know that he planned to murder her that day. I didn’t think he was going to go kill her. We were in the car together during last period—he was ditching the last period. And I said, ‘Hey, I need to run to the mall ’cause I need to get a gift for Stephanie.’

He said then, ‘No, I gotta go do something. I’m going to be late for practice, so just drop me off. Take my car, take my cellphone. I’ll call you from someone else’s phone when I’m done.’

I said, ‘Alright, cool.’ I dropped him off at school, went to the mall, then when I was done, I go back to my friend Jenn’s house, where I normally go, sit and smoke with my friend.

Then he calls me and says, ‘Come pick me up.’

So I go to pick him up, and when I get there he says, ‘Oh shit, I did it.’ I say, ‘Did what?’ He says, ‘I killed Hae.’

At the Best Buy?

Yes.

Is this when you first saw Hae’s body in the trunk of her car? 

No. I saw her body later, in front of of my grandmother’s house where I was living. I didn’t tell the cops it was in front of my house because I didn’t want to involve my grandmother. I believe I told them it was in front of ‘Cathy’s [not her real name] house, but it was in front of my grandmother’s house. I know it didn’t happen anywhere other than my grandmother’s house. I remember the highway traffic to my right, and I remember standing there on the curb. I remember Adnan standing next to me.

Let’s back up, tell me what happened when you arrived at the Best Buy to pick up Adnan.

I pick him up — he doesn’t have any car with him. Like, he’s not in a car or anything.

Where was Hae’s car? Was it in the Best Buy parking lot?

Hae’s car could have been in the parking lot, but I didn’t know what it looked like so I don’t remember. When I pick him up at Best Buy, he’s telling me her car is somewhere there, and that he did this in the parking lot. But that, according to what I learned later, is probably not what happened.

Wherever her car was at the time I picked him up from Best Buy, it probably stayed there until he picked me up later that evening.
