Shelbey Thornburgh’s killer caught on cctv, FBI has classified it as potentially a "serial" offender.

Hi guys, first post here. I'm trying to help a victim’s sister get some renewed media attention!

Shelbey Thornburgh (SW Houston, 2015). Killer on CCTV. She was a 20-yr old sex worker & he made a "date" with her from a Backpage ad. In her apartment for only 17 minutes & slashed her throat before casually strolling back out. Used a burner & contacted ~20 girls hunting a petite blonde. FBI picked it up as just 1 of 25 publicly listed in Vicap (suspected serial killer). Pimp was thoroughly investigated & LE has no interest in him as a suspect or someone who "had her killed."
There's DNA but no Codis hits after 8 years & the profile isn't sufficient/ideal for genetic geneaology, but investigators are seeking approval from TX DPS Codis Advisory Board to allow a familial search.

I’ll include several links to law-enforcement/tip info in the comments as well as a few podcasts, and YouTube videos that I think did some good coverage of Shelbey's case. This case is totally solvable, but hardly anyone in Houston has even heard of it.
H-Town please help get this dude's pic seen.
Potential ties to Sugarland/SW Houston area.
