The search for a man accused of killing his family in Waller County has ended.
Investigators arrested Trey Sesler in Magnolia, around 9:30 p.m. Tuesday.
Waller police began looking for Sesler, 22, after his parents and brother were found shot to death inside their Waller County home in the 1600 block of Farr Street earlier in the day.
Family members called police and asked them to check on the Seslers because they hadn't heard from them. Waller Police went to the home, and that's when the gruesome discovery was made.
"They were walking around looking in the windows," Waller County Sheriff Glenn Smith said. "They could observe what appeared to be a deceased male."
Once officers made entry into the home, they found two more bodies. All of them had been shot multiple times, investigators said.
The three victims are Lawton Sesler, his wife, Rhonda, and their 25-year-old son, Mark.
Waller Police Chief Phil Rehak described the inside of the house as a "war zone," and said it's evident a violent crime took place.
Detectives immediately suspected the couple's younger son, Trey, was responsible for the killings, and they began to search for him.
"Evidence was obtained and it was pretty obvious -- the connection of the other brother and son to these people," said Smith.
Investigators said they don't know the motive, although there are some reports that a domestic argument took place at the home the day before, and neighbors reported hearing gunshots around 5 or 6 p.m. on Monday.
Officials said they were concerned Trey Sesler may have been armed and they considered him dangerous.
"There was a high-caliber rifle used at the residence, and it has not been located," Smith said before the arrest. "We obviously feel he may still have it with him."
Smith said that Trey Sesler had recently inquired about body armor.
Lawton Sesler, the oldest victim, had family living just down the street. His aunt, Weda Frierson, lived only a few houses away.
"I saw the police tape and I knew that meant something very serious had happened," said Frierson.
She said that her nephew kept certain family matters private, but she was aware that his son, Trey, had been undergoing some kind of "treatment" and was on medication.
"I'll have to admit he was quite strange," said Frierson. "Trey almost acted as though he didn't know us. He would be walking down the street and, of course, the ordinary thing you'd want to wave at your nephew, but he wouldn't look our way."
That strange behavior Frierson described may have been demonstrated online. Waller police identified Trey Sesler in a series of web blogs that were posted to the website YouTube. In them, he talks about cartoons and refers to himself as "Mr. Anime."
Trey Sesler also had a Facebook page where a picture was posted of him aiming a gun directly at the camera.
Relatives said Lawton Sesler was an elementary school teacher and that Rhonda Sesler worked at a local newspaper.
"I know my nephew was a Christian," Frierson said. "They're in heaven, and I think that's the greatest comfort a family can have."
Rehak said deputies in Montgomery County along with the Texas Department of Public Safety and Texas Rangers helped capture Trey Sesler, but it's unclear what we was doing in Magnolia.
Trey Sesler has been booked into the Waller County Jail and is being held without bond.
