Oswald or someone who looked like Oswald was seen at the window on the Sixth Floor.
There was someone who looked similar to Oswald seen fleeing the SBD that day.
There were multiple occasions in days days prior where someone who identified himself as Oswald. One event that comes to mind is that someone claiming to be Oswald went to a car dealership and test drove a car (Oswald didnt drive). In many of those sightings, that ‘Oswald’ was described as being 5’6”. The original Oswald was closer to 5’11”
