“Unless she got out of the car and then finished him off as he lay on the pavement.”
That’s certainly what it is looking like to me, since there is only one bullet hole in the car window. If there are two holes in him, then that second bullet obviously didn’t teleport through the window.
There is a question as to whether that car shown on the website with the one hole in the wondow belonged to the shooter or whether it was the one that the bullet struck as it ricochetted around.
Maybe the second shot went through the hole made by the first or only slightly enlarged it. I haven't seen any closeups of the window nor any forensic analyses.
