STURGIS, Mich. — It took South Florida investigators 20 years to finally close the case involving Adam Walsh, the son of TV personality John Walsh.

Eleven years ago, 6-year-old Brittney Beers vanished from her apartment complex. While the case is open, investigators have found no new leads; but they're determined, just like Florida detectives, to close the case.

And since 1997, when Beers vanished, detectives have received thousands of tips.

While the times have changed, some of the familiar places are still around and the circumstances surrounding the suspicious disappearance of Beers from the Village Manor apartment complex also linger.

"It wasn't late at night or early in the morning, it was maybe five or six o'clock," recalled Sturgis resident Patricia King.

Sturgis Deputy Police Chief David Ives said detectives are still investigating.

"People don't forget and we sure don't," Ives said. "It's important to officers here now, and those that retired."

Beers has appeared on the National Center for Missing and Exploited Children's website along with 4,500 others across the country.

The Sturgis community remains optimistic, looking at Adam Walsh's case in South Florida, which finally closed after 27 years.

"If it takes 20 years, sooner or later they'll find who took that child and where she's at," said Sturgis resident Barbara Harris.

"It's not over," Ives added.

Sturgis Police follow new developments and review evidence.

An age progression photo was released Tuesday. It has already appeared on the National Center for Missing and Exploited Children website.

"We just wish we could find out what happened to her," said Sturgis resident Sonya Saddison. "I know the whole town is waiting on it."

Ives said detectives and the FBI meet regularly to review the case, combing through every detail to ensure nothing was overlooked.

Most cases remain open until a child is recovered.
