This is the stuff nightmares are made of. New Mexico teen Nehemiah Griego, who is 15, has been accused of killing his parents and three siblings -- first his mother, Sara, then his 9-year-old brother, then his 5-year-old and 2-year-old sisters. He then waited hours until his father got home -- and killed him too. All with the family's own arsenal of guns.
Griego, who lived in New Mexico with his family, was reportedly "annoyed" with his mother and so he waited until she was asleep before taking one of the family guns -- which were apparently not locked away -- and shooting her in the head. When his 9-year-old brother, Zephania, who was sleeping with her awoke from the sound, his brother informed him that their mom was dead. When the boy said he didn't believe it, Griego reportedly lifted up his mother's bloodied head before shooting his brother.
His sisters, awakened by the noise, then reportedly began crying. The police report states: "Nehemiah stated he lost his sense of conscience and went to the bedroom his two younger sisters share. Nehemiah stated when he entered he noticed that his sisters were crying and he shot both of them in the head."
