Alanna Gallagher's biological father said he was glad to have spent nine hours at the Saginaw Police Department to help in any way with the investigation.
Police don't have any suspects, including family members, in the 6-year-old's death investigation.
Miles McDaniel wants to put suspicion rumors to rest. "I know the odds are high it's a family member in this sort of situation, anyone that knows our family knows better," he said.
It's been eight days since his daughter's body was found two miles from the family's home.
Witnesses say Alanna's hands and feet were bound with red tape, a garbage bag covered her head and a tarp tied with a belt enveloped her half-naked body.
Miles McDaniel said he last saw his 6-year-old daughter as she left the family's home to go play with a friend but he wouldn't say when that was.
He says he now regrets ever letting her leave.
According to the FBI search warrant returns, investigators took 109 items from the house including toothbrushes, toilet paper, garbage bags, tape and DNA samples.
From the family's three cars, they took a medication, garbage bags and a tarp.
Saginaw police have never said any of Alanna's three parents were suspects. However, McDaniel believes they asked him to come in to compare stories.
"There were a lot of questions. I expect they were probably cross-checking answers that had been given by Carl and Laura when they were giving their interviews," said McDaniel.
He describes his relationship with Alanna's mother Laura Gallagher and her husband Carl as polyamorous. McDaniel doesn't question the other two in Alanna's murder.
"Anybody who knows the family knows there are three parents in the family. You can talk the school, you can talk to the church, you can talk to the dojo, everybody knows," said McDaniel.
He says all three parents have the same mission. "I want to find out who did this, I want justice and I hope that they can be found," said McDaniel.
