BOISE, Idaho (AP) — Sheriff's deputies have interviewed more than a dozen girls named "Destiny" trying to crack a vandalism case where someone spray-painted a prom invitation on a southwest Idaho cliffside.

But Ada County Sheriff's Office spokesman Patrick Orr tells KBOI-TV in a story Thursday that the case remains unsolved. Authorities in May discovered the message "Destiny, Prom?" painted in large pink and blue letters on the side of the Black Cliffs, a popular rock climbing spot, east of Boise.

The person could face a misdemeanor charge of injury by graffiti, which is punishable by up to six months in jail and a fine of $1,000. The sheriff's office says new leads might emerge now that school is back in session. Officials have painted over the graffiti.
