According to a probable cause statement, the teen told a detective he first shot his mother as she was sleeping and then shot a younger brother in the same room and then two younger sisters in another. His shot is father when he came home, according to the statement.

ALBUQUERQUE, N.M. — The New Mexico teenager accused of fatally shooting his parents and three younger siblings told police he had been having homicidal and suicidal thoughts.

According to a probable cause statement, a Bernalillo County sheriff's detective questioned 15-year-old Nehemiah Griego on Saturday about the killings at the family home in a rural area southwest of Albuquerque.

The statement says Griego told the detective he first shot his mother as she was sleeping and then shot a younger brother in the same room and then two younger sisters in another.

It says he then told the detective he waited for his father to return home and then gunned him down.

Sheriff's spokesman Deputy Aaron Williamson said Monday he couldn't immediately comment on the document.
