A records check by the Children, Youth and Families Department indicated no problems with the Griego family and that Nehemiah Griego had never been in trouble with the law.
Sheriff’s Deputy Aaron Williamson confirmed there was no history of any emergency calls to the home in the recent past.
‘‘This is beyond any human reasoning or understanding,’’ Houston said.
‘‘It’s horrific. What other words do you use? This is certainly the first time that I have been into a crime scene with this much destruction at one home.’’
In addition to the two rifles, there were two 12-gauge pistol-grip shotguns in the home, Houston said. Griego’s father had taught him to use guns, and they shot together on a regular basis, Houston said.
The house had a security-style sign outside saying ‘‘Protected by Smith & Wesson Security Services.’’
