Jouett is currently detained at a juvenile detention center.
It was about the same amount of time Stevens said Jouett had been dating his daughter. "I'm blown away by him snapping and doing something like this. He had all kinds of plans and ideas to help us at the church." Stevens said Jouett attended both Sunday morning and Sunday night services at the Clovis congregation on the day before Monday's shooting rampage."The Clovis-first model says it would have taken anywhere from 700 to 1,000 years for people to reach the southern tip of South America," Waters said."It seems highly unlikely that the Clovis people could have flown down there in 200 years.Stevens said out of respect for Jouett, he would not reveal the details.But a close family member of Jouett's who identified himself to KOB on Monday -- and offered details to corroborate his relationship to the accused shooter -- said the teenager struggled with a methamphetamine addiction from the age of 13.The Living Word Church of God pastor told KOB on Tuesday that the juvenile accused in Monday's library shooting -- 16-year-old Nathaniel Jouett -- had been attending the church and dating his daughter.
Stevens suggested Jouett's recent happiness was a newfound reprieve from a difficult, and at times even abusive, childhood.
"He'd come over to the house afterward for about an hour," Stevens said.
"And he was fine." Stevens said there was no indication Jouett was planning to act out violently. They had a great relationship." But Stevens also acknowledged he was fully aware of Jouett's troubled past.
Radiocarbon dating had previously shown the Clovis period to range from 11,500 to 10,900 radiocarbon years ago (about 13,300 to 12,800 calendar years ago), giving the culture several hundred years to reach South America.
Radiocarbon years and calendar years don't always match, because the atmospheric abundance of carbon 14—which is absorbed by all living things and on which radiocarbon dating is based—has varied over time.
"Now we can perhaps begin to ask new kinds of research questions," Dillehay said, "about the timing of this existing population, about migrations and movements, and what's going on in North versus South America."
