Well we do know for sure he was at the Subway. Just spitballing here but I wonder if he could have got the bleach stain from the subway bathroom, often fast food joints keep janitorial stuff in the restroom for later cleaning. Could probably have gotten makeshift rope from there too
Good point!
Or a confederate at Subway to supply him.....................
They’ve probably checked already, but it would be interesting if Subway had video footage of the guy walking in nice and clean, hitting the men’s room, and walking out all bleached — just before going to the sidewalk to be “assaulted”.
