CLEVELAND — Sunday will mark 30 years since the death of Amy Mihaljevic.

While her case remains cold, the FBI is making a new effort to find tips.

The bureau has posted electronic billboards across the area, asking anyone who may know something to give them a call.

While agents wait for answers, 3News has produced a special series of stories on the Mihaljevic case with Andrew Horansky. You can see the first story Wednesday night on What's Next at 11 P.M.

Our team has also produced a podcast called "Amy Should Be Forty."

You can listen to a preview right now wherever you get your podcasts, including Spotify. The full series will be available on Sunday.
