ALPENA — Duane Bills has no idea what happened to his daughter and no clues that might help him find out, so he’s pleading with the public to come forward with any information that might bring any answers.

No one has seen or heard from Brynn Nicole Bills since Aug. 1, her father said Thursday. And, while he said police have actively pursued several tips, “nobody seems to have a clue” what happened to her.

“We’ve got nothing,” Duane Bills, of Fairview, said Thursday. “We have no hardcore proof one way or another.”

Brynn Bills lived in Alpena and was last seen in this area.

The father and police urge anyone with any information to call the Michigan State Police-Alpena Post at 989-354-4101 or the Alpena Police Department at 989-354-1800. Duane Bills described his daughter as between 5-foot, 2-inches and 5-foot, 3-inches tall, with sandy blond hair and blue eyes, a slender build, and a bubbly personality.

She turned 18 on Aug. 12.

She did not have a vehicle, and Duane Bills said none of her friends have reported seeing her since the start of last month, “and that’s pretty odd.”

Police consider Brynn Bills a missing person and “detectives are actively investigating and they’re following up on any leads,” said Michigan State Police spokesman Lt. Derrick Carroll.

He refused to provide additional details because of the ongoing investigation.

Duane Bills said the family and police have considered organizing a search party, but “we gotta have a spot to look,” and they’ve received no information to point in any direction.

He said the family will offer a substantial cash award for any verifiable information that leads to a solution to the case.

“We’re just trying to find the whereabouts, what transpired,” the father said Thursday. “If anybody has any leads, any information, we’d like people to come forward. We’d like to find her alive, of course, but, if something stupid happened, we don’t want something to happen to someone else’s kids.”
