Authorities have arrested a 22-year-old man whose parents and brother were found dead in their East Texas home.
Trey Sesler was taken into custody around 9:30 p.m. Tuesday.
After getting calls from concerned family members, authorities said they went to a home about 1 p.m. Tuesday in Waller. There, authorities say, police found the bodies of three people who appeared to have been killed by shots from a high-powered rifle.
Waller County Sheriff Glenn Smith says the house had been ransacked.
The victims have been identified as Lawton Ray Sesler, Rhonda Wyse Sesler and 26-year-old son Mark Alan Sesler.
Waller is located about 40 miles northwest of Houston.
Trey Sesler maintained an active YouTube account on which he posted reviews of Japanese animation and called himself "Mr. Anime."
