The reporting on how he came to be arrested is quite a bit different from what's all over social media. From what I've read, it wasn't until the cops showed up that anyone even knew who it was. It seems like he was acting strange after several days on the run and nights without much sleep. A concerned customer asked an employee to call the cops.
I don't know how accurate this story is, but I have no idea where the social media narrative came from, except that it was half written before he was ever captured. I think the anger at McDonalds and the employee involved is misplaced, and I hope it doesn't have serious consequences.
