A bit of thought on this...
LEO’s left eye was damaged and not functioning normally.
LEO is right handed.
Perp had wounds / shots on his right side.
Last I was taught (admittedly, hunting classes in the 70s), you line-up the weapon under your dominant eye, track the target ^with both eyes open^ and squeeze the trigger.
The damaged eye may have caused a left-ward (over) compensation for LEO Wilson; that may explain the number of wounds to the perp’s right side.
An additional scenario is that LEO “ran the ladder” on the perp to “stop” him; starting low (leg region) and ending at center mass. Given the number of perforations, the perp may have (a) stumbled forward, or; (b) started to collapse, presenting his head in the COM target area.
ay Wilson could have taken an earlier headshot...but he just couldn’t do it. He went for the mass.....

I thought one started for center of mass first.
