The police had the initial thought that Dale suffered from some sort of stroke or medical issue (which is weird because they searched the building and couldn’t find his body) so they brought in a dog to track his scent. Dale’s scent was tracked throughout the plant — even deviating from his usual security route and ending up at the glass furnace. Of course, the immediate thought was that Dale’s body was incinerated in the furnace — especially because the dog picked up no further trace of Dale after that point. The police ruled that out, though, since the furnace hadn’t even been switched on that night. Next, the police checked out the security tapes.
When the police looked at the security footage they almost immediately saw a masked man with a winter coat walking around the back of the plant. At some point, that masked man is seen conversing with Dale but there isn’t really indication as to whether that seemed like a volatile conversation or not. The masked man then coerces Dale to begin walking with him toward the second floor’s exit. As they are leaving, Dale looks directly into the security camera, which soon became a topic of debate. The last time the camera picks up the masked man, he is seen wheeling a large bag out of the building — a bag that most likely contained Dale’s body. Well, that depends on what theory you think is the most believable.
