FWIW, the news story also reports:

Investigators declined to elaborate on the nature of the household dispute, but said a family fight happened on the night of the killings.

“There was an ongoing internal situation within the dynamics of this family,” said Texas Ranger David Maxwell.

Thomas' sister, Ka'Tara Price, 24, of Houston, said she believes anger and Thomas' conversion to the Muslim religion influenced his actions. She said she is not aware of him suffering from any mental illness.

“It's anger and pure evilness,” Price said Wednesday night. “He's always been a very angry person. If he thinks he's right, he's right.”

Price said another family member told her that her brother had a disagreement with their mother before the killings, but she doesn't know what it was about.

“I don't know what in this world could trigger him off to do a thing like that,” Price said. “I just want to know why.”

Investigators said they have not yet received blood test results to see whether he was under the influence of illegal drugs or alcohol that night.

IMO, Texas Rangers are better trained and equipped than bloggers to perform criminal investigations. YMMV.
