Dalton Jack, however, is unsure if he is a person of interest in the disappearance of the 20-year-old Iowa State University student, who went missing a month ago from her tiny hometown of Brooklyn, Iowa.
"You know they got to clear all their bases," he told RadarOnline.com. "They got to start eliminating stuff before they start narrowing in. I understand that entirely. If they need to check me out or anybody else out, they'll pretty much check you off the list. I'm more than willing to comply."
Being kept in the dark by authorities isn't unusual in this missing person's case, which has captivated the nation.
Mollie went jogging in a seemingly safe, obscure agricultural town of 1,400 residents on July 18, and has never been heard from since.
The 20-year-old is loved by all who say they know her. She has been described as a spunky, positive-natured young woman who was an outgoing and a visible presence at her high school. She was on her second year at Iowa State.
Authorities consider her disappearance after going for a jog around 7:30 p.m. "suspicious."
When asked who administered the polygraph test – the Iowa Division of Criminal Investigation or FBI – Dalton couldn't answer.
"I don't know who it was," he admitted. "I don't know what department it was. I don't know what I'm allowed to tell you on that situation and what I'm not, because obviously they didn't make it public."
Spokespersons for state and federal authorities declined to confirm the polygraph.
"With this being an on-going investigation, we will not be discussing any investigative information at this time" a spokesman for the Iowa Division of Criminal Investigation told RadarOnline.com.
Meanwhile, Dalton insisted he was going to help find his girl. When asked about a theory that alleges a villain is holding Mollie, the determined boyfriend was reminded of another fiend, and the horrors he inflicted on unsuspecting victims.
"Well you know, I'm not going to count that out," he said. "When John Wayne Gacy was a serial killer in his community for 20 years… nobody thought anything of him. I'm not going to count any of that out. I'm not going to say there's a person like that living in my community. I'm not going to say that there is."
Gacy, who dressed as a clown at charitable fundraising events he helped promote in his community, was accused of sexually assaulting and murdering more than 30 victims in Illinois in the 1970s. He was sentenced to death and executed by lethal injection in 1994.
Dalton encourages anyone with information, no matter the scrutiny that comes with law enforcement, to come forward, and to not speculate any further from there.
"Innocent people aren't going to keep coming forward with information if they think they're going to get thrown over the fire every single time that they do that," he said. "Let people say what they need to say. If the authorities think it's of interest, then let them do that. You don't need to be making any of your own theories on that."
