It’s been nearly three months since Mary Wegner appeared on the “Dr. Phil” show to talk about her long-missing daughter, Laurie Depies.

It was an opportunity to introduce millions of viewers nationwide to the mysterious 1992 case of Depies, an Appleton woman who was 20 when she disappeared after driving to an apartment complex.

Wegner was hopeful that the show would lead to a breakthrough in the investigation into Laurie's whereabouts.

That hasn’t happened.

Wegner hasn’t heard anything lately from the Wisconsin Department of Justice, which is looking into Laurie's disappearance. She received only a few Facebook contacts, including one from a psychic, but that went nowhere.

Still, Wegner doesn’t regret appearing on “Dr. Phil.” She believes the more information out there about Laurie, the better.

“I’m glad I did it,” Wegner said of the interview that aired on Jan. 26 on OWN. “A whole new generation of people” is now aware of Laurie’s disappearance, she said.

Depies vanished after parking her car in a lot near her boyfriend’s apartment in the town of Menasha (now Fox Crossing) on Aug. 19, 1992. Authorities said previously that she worked a shift at the Graffiti store in the Fox River Mall, left the store shortly before 10 p.m., walked to the parking lot, got into her 1984 Volkswagen Rabbit and drove to the apartment.

Depies never made it to the apartment. Police were called later that night, and her parents were informed the next day. The only solid physical evidence was her car and a drink container found on the roof of the car. Examinations of the car and the cup didn’t lead to an arrest.

The case has been largely inactive in recent years but heated up considerably in November 2010, when Larry Hall — who is serving a sentence for kidnapping a 14-year-old Illinois girl in 1993 — dropped a bombshell by confessing to kidnapping and murdering Depies.

Suddenly, Hall was the prime suspect and authorities were hopeful there was evidence tying him to Depies. That evidence never materialized, and his confession has never been proven or verified.

Wegner, who lives near Amherst Junction between Stevens Point and Appleton, flew to Los Angeles in October to tape the show.

Wegner said she was encouraged by investigators to appear on “Dr. Phil” and tell Laurie’s story. But state law enforcement officials won’t discuss what — if any — impact the show had on the investigation.

Rebecca Ballweg, deputy director of communications and public affairs for the state justice department, told USA TODAY NETWORK-Wisconsin via email that detectives on the Depies case “are not available for interviews because this is an active and open investigation.”

“We are seeking any tips or information people may have or remember about this incident,” Ballweg wrote.
