The father of a 6-year-old girl killed last week says his unconventional family, which includes him, the girl's mother and her husband, are doing their best to hold together.
The father of the Saginaw, Texas, child who was found dead last week said his polyamorous household is doing its best to hold together in wake of the girl's killing.
Miles McDaniel, the father of 6-year-old Alanna Gallagher, spoke for the first time about his daughter's death and their family.
"I want to find out who did this," he said Tuesday shortly after speaking with investigators for a few hours. "I want justice. And I hope that they can be found."
The family includes him; Gallagher's mother, Laura Gallagher; and her husband, Karl. McDaniel said he knows neither of his spouses committed the crime, saying theirs is a loving family.
"Anyone who knows the family knows that there are three parents in the family," he said. "If anyone is interested, Google polyamory."
Police have said that the family is not suspected in Gallagher's death.
"I know there's always that suspicion -- I know the odds are high that it's a family member in this sort of situation," McDaniel said. "I can say that anyone who knows our family knows better."
He said he doesn't have information on any progress in the case.
"I know they are processing all of the evidence that they found, and they're doing their best," he said.
Gallagher's body was found wrapped in a tarp in the middle of a street about a mile from her home on July 1.
"The last time I saw Alanna, she was wanting to go play with friends, and I let her," McDaniel said.
He said he second-guesses his decision to let her go "every minute," saying that, "if I had just said no, she'd still be here."
