ALBUQUERQUE (KRQE) - According to new details released the teen accused of murdering his parents and three young siblings was planning to carry out even more carnage in a public arena.
15-year-old Nehemiah Griego made up several stories before finally confessing to authorities that he had killed his father, Greg Griego , mother, Sara, and three young siblings Jael, Angelina and Zephania.
Nehemiah had at first told authorities he had come home after being at a friend's house and found his family dead. He said that after finding the bodies he took the family van and drove to Calvary Church where he told his girlfriend that his family had been killed in a car crash.
When authorities asked why he had not called 911 the teen said he had panicked.
The teen also changed his story several times regarding why he had rifles in the cargo area of the van.
Although finally after Griego was informed by questioning officers that his story was not making sense, the teen started to tell authorities what had taken place.
Griego said he had been annoyed with his mother and was having homicidal and suicidal thoughts prior to the killings. He said on the evening of the murders he had taken a rifle from his parent's closet and used it to first kill his mother. He then killed his younger brother and two younger sisters. The teen then waited for his father to come home and around 5 a.m. Greg Griego did just that. Nehemiah says he waited for his dad to walk past him several times before he shot his father multiple times with a separate rifle.
The teen told authorities after killing his family he reloaded his weapons so that he could "drive to populated area to murder more people." He expressed a desire to shoot people at random and eventually be killed while exchanging gunfire with law enforcement.
Luckily he didn't make it that far.
After giving police the information above he was placed under arrest and is being charged with two counts of murder and three counts of child abuse resulting in death.
