Investigators who went directly to Griego's house found the five family members dead at the home. Griego was found with a .22 rifle, an AR-15 rifle, two shotguns, and rifle ammunition in his van around the same time. After initially denying to police that he had anything to do with the murders, he admitted to killing the family members out of "frustration" with his mother.from Alleged Teen Killer Nehemiah Griego's Girlfriend Cleared in Family Murders
He also told police he planned to shoot up a Walmart after killing his family, and that he also planned to kill his girlfriend's parents.
"Nehemiah said after killing five of his family members he reloaded the weapons so that he could drive to a populated area to murder more people," read a police report from the incident released Tuesday.
"Nehemiah stated he wanted to shoot people at random and eventually be killed while exchanging gunfire with law enforcement," the report said.
"We are deeply concerned about the portrayal in some media of Nehemiah as some kind of a monster," said the statement. "It is clear to those of us who know and love him that something went terribly wrong. Whether it was a mental breakdown or some deeper undiagnosed psychological issue, we can't be sure yet. What we do know is that none of us, even in our wildest nightmare, could have imagined that he could do something like this."
One way to explain this apparent sudden change in character would be a case of overshadowing by Spirits of Darkness, who seem to have a tendency to use people to conduct such wild "kamikaze"-type attacks. Note the proximity of Albuquerque to ley lines, where Satanic spirits (among others) are concentrated, and that the attack makes sense from the perspective of the anti-human, anti-Christ Spirits of Darkness. (Note that all of Andrea Yates' children were named after famous Biblical figures.) However, there might be some more conventional psychological or neurological explanation.
