WALLER, Texas (KTRK) -- Before social media influencers became household names, a young man in Waller was building a following on YouTube under the name "Mr. Anime." Trey Sesler made videos about anime and homemade movies, sometimes featuring friends and family.

But in March 2012, the 22-year-old became known for something far more disturbing - the murders of his parents and brother.

Rhonda, Lawton and Mark Sesler were found shot to death inside their family home.
