There is no car in my scenario. E&X and perpetrator walked the half block from the frat house home to Kings road coming up in back of the house.
I think they came in the back way, that is why the Ring camera shows K&M arriving home but not E&X. I never said they returned in a car or that the perpetrator drove a car to the residence. He simply walked back to the frat house later.
If the white Hyundia was on Taylor whoever driving it may have seen E&X with the perp going to Kings RD or perp returning to frat house. Maybe this is why LE says whoever is in that car has crucial evidence. They saw the perp crossing Taylor to or from Kings Rd.
if it was someone even loosely associated with the victims, wouldn't someone, somewhere in their sphere report that they know someone who drove or drives that car?
Maybe the person who drives that car is not in their sphere and is simply someone going to or from work. Or a party.
I personally think that LE has the wrong make and model car. Maybe even the wrong color, as an ivory, light yellow or silver car can look white at night under street lights.
This is all just my opinion.
