PHOENIX (3TV/CBS 5) -- It's a heartbreaking story that will never make sense. Especially to the distraught dad, who can't understand why the mother of his kids, Rachel Henry, would murder their three small children in their Phoenix home last week.
Pedro Rios talked about the family tragedy for the first time. "I'll never get to see my kids smile or laugh," said Rios. "I wont get to teach them to ride a bike or read a book."
Rios claims he had no indication Henry would do something like this. The couple and their kids had recently moved to Arizona from Oklahoma and were doing fine living with his aunt in Phoenix, according to Rios. Then - the unthinkable happened.
Rios said he came home from work January 20th and played with his two older kids for about a half an hour, before their mother told him she was going to put them down for a nap.
Rios said he dozed off, and after he woke up was on the phone with his grandmother. Moments later, he pulled back the sheet from his youngest daughter, who he thought was sleeping on the couch. She wasn't moving.
"I picked her up and was like, grandma, what do I do?" said Rios. "She was like, give it CPR, and I said I don't how." Rios remembers running outside to get his aunt, who discovered the other two children. "It hurts me that I didn't even realize my other two kids lay next to me," said Rios. "I just seen my daughter, my smallest daughter."
Court papers state that Henry admitted to smothering all three of the children and then laid them on the living room couch as if they were taking a nap. Henry never told the other two people in the home what she had done. Rios said she acted like nothing had happened.
"Just tragic," said Rios. Police reports from Oklahoma indicate that Rios had a volatile history with Henry and his children. Henry previously accused him of threatening her.
