Something I am curious about: were there working surveillance cameras inside Lane Bryant at the time? I may have missed it in a comment in this thread, but that’s something I am curious about. I know there was surveillance video outside of the store, but I am not sure about the inside of the store.

Gotcha.

Thing is, they do have his DNA, and they do have his fingerprints. However, if they have fingerprints, that tells me this person has not been in trouble with the law before. Some takeaways I have from the case:

1) The killer had some level of intelligence. He was able to pose as a deliveryman for 15 minutes before he robbed the store. He was largely able to keep everyone’s guard down until that point.

2) The fact that it’s suspected he was trying to accumulate as many hostages as possible tells me he was desperate for money. I don’t think it was necessarily due to drugs, either. He was able to plan this out thoroughly, and someone on drugs would act more spontaneously.

3) I am almost wondering if he had visited the store before the murders. The reason I say that: It just seems odd that he would hit the one store without security cameras in 2008 (a time when surveillance cameras, although not as widely accessible today (I.e. Ring camera systems, etc.), they were still extremely common in most stores.

4) Assuming this person has never been arrested, then DNA is the best available tool. However, it almost sounds like they do not have enough of a sample for testing, because if they did, we would likely have seen a suspect arrested (possibly through DNA family tree testing).

5) I believe the composite is likely accurate. Keep in mind: the killer was in the store for 40 minutes, so the survivor likely got a very good look at him.
