New Mexico teen who killed family also planned to attack Walmart

Albuquerque, NM, United States (4E) – The 15-year-old boy who fatally shot his mother, father and three younger siblings in their house near Albuquerque, New Mexico Sunday has informed police he planned to shoot up a local Walmart after killing his family to start a mass destruction.

Police said Tuesday that Nehemiah Griego revealed plans to kill his family, his girlfriend’s family, and local Walmart shoppers for weeks before he began his shooting spree Sunday.

The Bernalillo County Sheriff’s Department claimed the boy started the massacre around 1 a.m. after he grabbed a gun from his parents’ bedroom closet while his mother, Sara Griego, was asleep and she became his first victim.

Griego then shot dead three of his younger siblings, ages 9 to 2, who were also at home. He then waited for his father, Greg Griego, to come from his overnight shift around 5 a.m. before shooting him multiple times with the AR-15 rifle, said Sheriff Dan Houston.

Houston revealed Griego then took two shotguns and ammunition, planning to head to Walmart to cause more disturbances but instead ended up spending the day with his 12-year-old girlfriend.

It was about 8 p.m. that day that the young pair headed to Calvary Church and someone on the church’s staff called 911.

“Nehemiah had been contemplating this for some time and the information about the boy’s plan about the local Walmart is accurate,” Houston said.

The girlfriend remained unidentified but police said the investigation is ongoing and would determine if she would face any charges.

Deputies arrived at the Griego home around 9:15 p.m. on Sunday and found the four bodies.

Police said Griego confessed to the crime and told investigators he was frustrated with his mother.

Officials said he faces murder and child abuse charges and will be tried as an adult.

The father was a former church pastor at Calvary Church in Albuquerque.
