That BG photo is like a Rorschach ink blot; I see so many different things, depending on when I look at it.
This time, as I look at the BG photo, I see the knee area and just below on his jeans looking slightly muddy, as if he had been kneeling. Anyone else see that? Could be so wrong, because with the pixelation, our brains tend to fill in the blanks. Many blanks in this case.
At this time, I can't relate to the second sketch and what we see in this blurry BG photo. I see much more of the first sketch, although it's likely he is a blend of both? Who knows. Last I recollect, the first sketch has been dismissed, or just still no clarity on that point?
I've been studying everything I can re: sexual homicide, although we don't absolutely know there was a sexual attack here - but I think it's a fair assumption. Sexual homicide represents a very small percentage of homicides overall, just slightly over 1% per this scholarly research:

(You have to scroll approx. 1/2 down page to get to actual study).
So if there was sexual assault involved in this murder, we know this Perp is a rare breed.
Motivators: Urge to sexually assault, or grievance towards women, or killing to avoid detection post rape
Types of Perps:
1. Power-assertive rape murder: Generally in 20's, with a "primative" emotional state, macho image, anti-social, high school dropout, property crimes. Motive is aggression and control. Victims are strangers, surprise attack. Crime scene reflects organized attack
2. Power-reassurance attack: living out rape fantasy. Socially isolated with limited history of normal sexual activity. Underachiever, likely criminal history which may include fetish, trespassing, larceny.
power-reassurance. Tends to pick victims 10-15 years older or younger than him.
3. Anger-excitation rape-murder: Average married guy on outside, private sadist. Collects *advertiser censored* with bondage and sadism. Selects strangers with con or ruse; well planned. Aim to inflict pain and tortue. Takes trophies
Editing to add that based on the few facts I do know about this case, profile #3 seems the most likely to me ATM.
The full article is a very worthy read as it relates to this case. Again, here is the full link:
