Oh I thought she went to Starbucks around 6:30 am before the garage sale? That is what was said on the podcast.
Yes, I don't remember the exact time, but you're right, she made a quick run to Starbucks right before the sale was supposed to start.
But I was talking about the theory you brought up about this possibly stemming from a road rage type of incident. At first thought, it would seem this wouldn't be likely, since we know the same truck was seen on video driving by Liz's house in the middle of the night before that morning's shooting. So it wouldn't be something that happened that very morning, like say during her Starbucks run, that led to the shooting.
But I was saying that it still could be possible that as you mentioned, a road rage type of incident could still be the reason she was shot, but only if it had happened sometime prior to the night before the shooting. What if she somehow made some short-fused person angry on her drive to or from work the day or 2 before the shooting? They could have followed her home or close to home without her even knowing. Then came back and shot her. Maybe they didn't actually follow her all the way home, but after they got mad at her for whatever reason, they went home and stewed about it, getting even madder, and decided to get revenge. So they went out that night before the shooting, and drove around in the area where they had last seen her, looking for her car, trying to find out where she lived, which would fit what we know they've seen on video from that night, before eventually finding her car parked outside her house. Now they knew where she lived. So they came back early in the morning and when they saw her outside, they got out and shot her.
This could be possible if the hypothetical road rage incident happened close to her home, AND when she was on her way in to work one morning. Because then the perp would know approximately what time she could be expected to leave for work, after having seen her on her way to work the morning of the road rage event. And if that event happened say, right as she left her neighborhood, they would know what neighborhood she likely lived in. Probably wouldn't take too long driving around the area looking for her car before they found it and would then know where she lived. And they'd know when she would be leaving for work, based on what time they saw her driving to work that previous day, since most people have regular work schedules, like she did. They could have found her house the night before and come back in the morning, waiting within sight of the house for her to come out. Then drove up, parked, got out and shot her.
I'm just trying to figure out how the garage sale fits in to this theory. So if it was something like this, then it was just a coincidence that she happened to be outside setting up the sale that morning. They would have been expecting her to leave for work, since they wouldn't know about the sale. But either way would have worked, not much difference for their purposes. Would have worked even better for them, in fact.
But would it also just have been a happy accident that they happened to arrive just after Sergio left? I don't want any one theory to require too many coincidences for it to work. But no, if they had parked nearby to wait for her to come out, they would have seen the van leaving, and assume that she was left there alone at that time. So they'd leave their spot as soon as the van left, which is exactly what we know they did. Except that they left their spot when the van left the house, but they didn't go right to the house at that time. They parked again nearby, waited I think a few minutes and then left for the house.
So there's one problem with that theory. IIRC, while they were parked in the school parking lot, they weren't in a position where they could see the house. So leaving the school at the same time that the van left the house would require another coincidence, which is probably at least one too many!
So it seems to me that's probably not what happened, although I do think it's possible, and AFAIK, it's not something people have theorized about, but I may just have missed it if it's already been brought up. I still do think it's worth considering that Liz and the shooter may not have actually known each other or had any mutual connections at all. All I've ever seen people talk about is theories that include only Liz knowing the shooter or someone Liz knows sending the shooter, except for people who wonder if it was some kind of gang initiation, in which Liz and the shooter would be strangers to each other in every way, but that isn't a possibility in my mind, mainly because of the recon the night before.
So this is still something to think about, even if it happened differently from how I described it. The hardest cases to solve I've always heard are stranger murders, since there simply are no connections to be made, so where do you even start the investigation? Easy to end up an unsolved cold case like Liz's unfortunately seems to have become, when there's no relationship between the perp and the victim. And the scenario I imagined above (inspired by
@Lisalong 's mention of a possible road rage event!) is one that doesn't require any relationship between Liz and the shooter. Which is the first time I've personally considered that that might be true. I had been leaning toward the shooter being someone sent by someone close to Liz, but had reservations about that too.
