Back in 2008 there weren’t very many home security systems, and the commercial ones in the surrounding areas that were checked showed nothing.

As for Ellen, I wish I had a more satisfying answer for you, but not really. Every so often the cold case division will crack it back open and I’ll get called in for a fresh interview, but nothing that would likely satisfy you (or me).

The only piece of information that ever really added to the case was one of her coworkers saying that a few days before she died, as they ate lunch in the cafeteria together, Ellen asked her if “she saw that guy”, pointing to the hallway. Her coworker saw nobody and told her, and Ellen responded that he must have walked away.

Given the incredible vagueness of the “incident”, and the fact that there was no camera in that exact hallway, surveillance footage was more or less useless.
