DENVER — This weekend marks a painful anniversary for the family of a missing Denver woman. 38 year old Amy Ahonen was last seen on July 8th, 2011. Her unlocked Jeep was found abandoned on US 6 in Clear Creek canyon on July 10th. Her purse, wallet and car keys were still inside.

Investigators originally thought Ahonen may have fallen in the raging river, but a search turned up nothing.

On Friday, Ahonen’s family flew in from Michigan to meet with Denver police detectives and get the latest on the investigation. “It’s frustrating,” Amy’s sister Andrea Ahonen told us. “Nobody knows anything and DPD still hasn’t figured anything out.”

Andrea suspects convicted killer, Travis Forbes, may have been involved in her sister’s disappearance. Forbes is currently serving a life sentence for murdering 19-year-old Kenia Monge, but he was out of jail when Amy went missing.

“(Police) talked to (Forbes) and he said he didn’t do it. But he said that before in (the Monge) case,” she said.

Family members also asked investigators to find the man who responded to a roommate ad Amy placed on Craig’s list. Amy thought he was so “creepy” she immediately took the ad down. Andrea said police searched Amy’s computer but found nothing.

A Denver police spokesperson told us there is nothing new in the investigation that they can release.

Still, Amy’s family is hoping the public can help them find her. “We want to find her, we want to know what happened,” Amy’s mother, Betty Ahonen said.

The Ahonen’s are holding a vigil for Amy on Sunday, July 8at the Epiphany Lutheran Church in Denver at 7:30pm.

The public is invited to attend.
