NORTON SHORES, Mich. (WZZM) -- Her face has been on TV, online, and in the newspaper for 10 days and despite the publicity, Jessica Heeringa remains missing.
"We're quite confident about the timeline, about the silver minivan," said Norton Shores Police Detective Sergeant Michael Shaw.
The 25-year-old mother disappeared from the Exxon gas station on Sternberg Road in Norton Shores on April 26.
"We know everything in my opinion except for the who right now," he said. And that's what's eating at Sergeant Kasher. "Disappointed in yourself and disappointed in how things have turned out-- it's always around you."
But Kasher is more disappointed in who he believes may be withholding information. "Somewhere along the line, that time around 11 p.m., the disappearance-- I truly believe someone knows something," he said.
"And I don't know the reason, but they don't want to come forward. Maybe it's their son, nephew, and they don't want to be involved." Or Sgt. Kasher says, maybe they have a record of their own. "We're not looking to get someone on some other charge, we're looking to get Jessica," he said.
"I guess if you don't have the heart to do that, and you're still worried about the police coming after you, let's not fear that part of it," said Kasher.
On the flip side, Kasher says there is information police won't share with the public because it may hinder their investigation.
"You start leaking things out and you start getting some false tips. And then we get someone in custody, we do want to go over that fine timeline or we want to go over that evidence because they'll know about that evidence."
But until police track down that evidence on their own, or through the help of someone else, the paperwork pile will continue to grow. And Jessica's family will continue to wait, and hope.
"There's nothing good about this case because we're missing a 25-year-old mom, daughter, family member and friend," Kasher said.
But he says his department has put every ounce of energy forward to solve this case, and they'll continue to do so.
"And by all accounts with the FBI and state police, it appears we have done exactly what they would have done. I was given the comment by one of the FBI agents there's nothing different they would have done, then what we have done from then to now."
The FBI and Secret Service are still helping with the case, but Sgt. Kasher says there's no more the FBI can do unless police can prove Heeringa and her alleged abductor passed state lines.
Sgt. Kasher asks anyone out there that is withholding information to call the police station and ask for him. He says you don't need to give your name, just the information.
