These are consistent with either a fall to the ground once he'd been shot - I am unable however to exclude that there hadn't been a fall to the ground prior to him being shot, it's due to any hard object coming up against that part of the body.  It could even be a punch, but it's more likely to be a fall to the ground due to my description of punctate.  In other words if one falls onto gravel or a tarred road and the surface is slightly rough, one would get that appearance.
	I mention too that some of the abrasions have a graze-like appearance, meaning that there had been a slight dragging possibly of the body, you know of the face on the hard surface.
