Sheriff: Teen suspect in murder of family learned to shoot from father 
 
 Bernalillo County Sheriff Dan Houston says murder suspect Nehemiah Griego learned to shoot from his father, and the two often went shooting together with guns that were not kept locked up in the home. 
 
 Houston revealed that fact during a grim news conference Tuesday that detailed the murders of five members of the Griego family Saturday in their South Valley home. 
 
 Nehemiah Griego, 15, is accused of killing his parents Greg and Sarah Griego, along with 9-year-old Zephania, 5-year-old Jael and 2-year-old Angelina. 
 
 The weapons used in the killings – a .22 rifle and an AR-15 rifle - belonged to his parents and were in the home legally, Houston said. Greg Griego, a pastor and former gang member, had an extensive record but was not believed to have ever been convicted of a felony, he said. 
 
 The sheriff said officers believe the teenager shot his mother as she slept at about 1 a.m. on Saturday morning. His brother, Zephania, 9, was awake and distraught and was killed after that. His sister Angelina, 2, was killed while asleep, but his sister Jael, 5, was awake when killed. 
 
 Griego then waited several hours for his father to return home between 5 and 6 a.m. from his job as a security officer at a rescue mission. The teen then ambushed his father, shooting him several times with the AR-15, the sheriff said. 
 
 Officers believe he had planned the attack for at least a week. 
 
 The teenager then loaded guns into the family car and planned to commit many more violent acts, Houston said. 
 
 Reports that he planned to go to a nearby Walmart, shoot people and then die in a shootout with police were accurate, he said. Officers believe the teen had planned the attack for at least a week. 
 
 Houston also said Griego may have intended to kill the parents of his 12-year-old girlfriend. Griego sent the unidentified girl a picture of Griego’s dead mother shortly after she was killed – and before he killed Greg Griego, the Sheriff said. It is not clear whether she will face any charges. 
 
 Instead of killing more people, Griego went to Calvary Church, where he spent several hours with his girlfriend and others. Greg Griego was a former pastor at the church and the family still worshipped there. 
 
 Griego apparently had no plans to hurt anyone at the church. 
 
 While he was there, Griego told church officials several stories about what happened to his family. Police were eventually contacted and discovered the bodies at about 9:15 p.m. Saturday. 
 
 Houston said Griego appeared “surprised” at his arrest and said he shot his family because he was annoyed at his mother. 
 
 He said Griego also told police he regularly played the violent video games “Modern Warfare” and “Grand Theft Auto,” although his parents did not allow it. It was not clear how Griego had access to the games. 
 
 Houston said Griego's demeanor was calm and that he did not appear to show remorse for killing his family. 
 
 "There is no best judgment of motive on our part,” Houston said. “It is beyond any human reasoning or understanding at this time." 
 
 Griego will appear in court Tuesday at 1:30 p.m. and will be treated as an adult. 
 
 New Mexico law allows prosecutors to charge children 13 and over as adults in serious cases, legal experts tell KOB.

 Griego, the 15-year-old son of an Albuquerque pastor, used two rifles to kill his mother, three siblings, and his father early Sunday morning, and loaded his van with the guns and ammunition he planned to use to shoot up a Walmart later that day, according to cops. 
 
 Griego also said he sent a picture of his mother's dead body to his girlfriend, whose name has not been released. Griego then spent the rest of Sunday with the girl and her family, according to police. 
 
 Griego and his girlfriend eventually went to Calvary Church in Albuquerque around 8 p.m. Sunday, nearly 18 hours after the spree began. There, Griego told church members his family had died in a car accident, prompting a church member to call police. 
 
 Police said Tuesday they were investigating whether the girl could face charges in connection with the crimes, but said today she would not. 
 
 "She has just been interviewed and she will not be facing any charges," Deputy Aaron Williamson, spokesman for the sheriff's office. 
 
 Investigators who went directly to Griego's house found the five family members dead at the home. Griego was found with a .22 rifle, an AR-15 rifle, two shotguns, and rifle ammunition in his van around the same time. After initially denying to police that he had anything to do with the murders, he admitted to killing the family members out of "frustration" with his mother. 
 
 He also told police he planned to shoot up a Walmart after killing his family, and that he also planned to kill his girlfriend's parents. 
 
 "Nehemiah said after killing five of his family members he reloaded the weapons so that he could drive to a populated area to murder more people," read a police report from the incident released Tuesday. 
 
 "Nehemiah stated he wanted to shoot people at random and eventually be killed while exchanging gunfire with law enforcement," the report said. 
 
 Relatives of Griego are described as stunned by his actions and "heartbroken over this senseless tragedy." 
 
 Though surviving relatives conceded in an unsigned "family statement" that Nehemiah Griego is a "troubled young man," the statement also described him as an outgoing boy who loved music and hoped one day to serve in the military. 
 
 "We know him as a bright, curious and incredibly talented young man. He was a brother, nephew, grandson and cousin," said the statement, obtained by the ABC News affiliate KOAT in Albuquerque from former New Mexico state Sen. Eric Griego, the suspect's uncle. 
 
 "We are deeply concerned about the portrayal in some media of Nehemiah as some kind of a monster," said the statement. "It is clear to those of us who know and love him that something went terribly wrong. Whether it was a mental breakdown or some deeper undiagnosed psychological issue, we can't be sure yet. What we do know is that none of us, even in our wildest nightmare, could have imagined that he could do something like this." 
 
 Griego is expected to face adult charges of murder and child abuse resulting in death. He waived his right to arraignment in adult court Tuesday and a judge ordered him held without bond. 
 
 The district attorney's office and Griego's public defender now are preparing to face a grand jury, KOAT reported. 
 
 "We never had a case like this, as far as I know, in the state of New Mexico," District Attorney Kari Brandenburg said, "so I can't compare this to any other case." 
 
 Griego has five older siblings who were not living at the home at the time of the shooting and were unharmed. 
 
 Eric Griego, the uncle who released the family statement, also released family photos late Tuesday, including one of his nephew in a tuxedo at a wedding and another of him playing a drum kit. 
 
 "From the time he was a young boy, his father Greg supported his love for music," the family statement said. "Thanks to his interest, practice and natural ability, Nehemiah has become a very accomplished musician. He plays guitar, drums and bass. For years he has played at youth and other church services at Calvary and elsewhere.

 "The idea that he was a loner also has been manufactured by the media and those who simply did not know him," the statement said. "He had many friends at Calvary where he spent most of his free time playing basketball or music. Like his father, who was a champion wrestler and coach, Nehemiah also competed in wrestling tournaments throughout the state and country." 
 
 The statement noted that several family members were military veterans. 
 
 "Pictures of [Nehemiah Griego] being circulated in his dad's old fatigues were part of his interest in someday being a soldier," the family statement noted. 
 
 The shooting spree began shortly around 1 a.m. on Sunday, when Griego allegedly snuck into his parents' bedroom while his mother, Sara Griego, was asleep. There he raided the closet where the family kept their guns, and immediately used a .22 rifle to kill her, according to the Bernalillo County Sheriff's Department. 
 
 Griego's 9-year-old brother was sleeping with his mother at the time and woke up. When Griego told the boy his mother was dead, the youngster didn't believe him, according to a police report. 
 
 "So Nehemiah picked up his mother's head to show his brother her bloody face," the report said. "Nehemiah stated his brother became so upset so he shot his brother in the head." 
 
 He then went into his sisters' bedroom, police said. 
 
 "Nehemiah stated when he entered he noticed that his sisters were crying and he shot them in the head," the police report said. 
 
 The girls were 5 and 2 years old. 
 
 The teenager waited for his father to come from his overnight shift working at a nearby rescue mission. When his father walked into the home around 5 a.m., unaware of what had taken place, Griego shot him multiple times with the AR-15 rifle, Houston said Tuesday. 
 
 Besides being a former pastor at Calvary Church, Greg Griego worked as a chaplain at a local jail where he counseled convicts. The family was very involved in the church, according to its website.
– Police near Albuquerque released new details about 15-year-old Nehemiah Griego, who is accused of shooting to death his parents and three siblings over the weekend: Griego shot his mother while she slept about 1am Saturday, say police. Then he allegedly killed his 9-year-old brother, described as "awake and distraught" at the time; his sleeping 2-year-old sister; and his 5-year-old sister, who also was awake. Police say Griego waited for his father to return from work about five hours later and ambushed him with an assault rifle, reports KOB. His father had taught him how to shoot. "The motive, as articulated by the suspect, was purely that he was frustrated with his mother," said Bernalillo County Sheriff Dan Houston. "He did not give any further explanation." Griego texted a photo of his slain mother to his 12-year-old girlfriend, and spent much of Saturday with the girl at a church where his father had been a pastor. It's not clear whether she will face charges. Griego likes violent video games, including Modern Warfare and Grand Theft Auto, but Houston didn't speculate on whether he thought that played a role, reports AP. Griego planned the attack for more than a week, but he abandoned his original intention of killing more people at a local Walmart.
