ALBUQUERQUE — The New Mexico teenager accused of fatally shooting his parents and three younger siblings told authorities he was annoyed with his mother and had been having homicidal and suicidal thoughts, according to a probable cause statement.
Nehemiah Griego, 15, was arrested following the shootings Saturday at a home in a rural area southwest of Albuquerque where he lived with his family. He remained in custody on charges of murder and child abuse resulting in death.
