IDAHO FALLS, Idaho (AP) — Relatives of a 2-year-old reported missing from an Idaho campground in 2015 are suing the private investigator they hired to help find the boy.

The parents and grandfather of DeOrr Kunz Jr. sued Klein Investigations and Consulting Tuesday in Bonneville County. KIFI-TV reports that the lawsuit alleges Philip Klein breached his contract by failing to share information.

It also claims he made false statements about the boy's parents Jessica Mitchell and Vernal Kunz, casting them in a bad light. Philip Klein said Friday that his firm had not yet received the suit and declined to comment on pending litigation.

The parents were named suspects by the Lemhi County sheriff, but no charges have been filed. No trace of the boy has been found since his parents reported him missing July 10, 2015 from Timber Creek Campground near Leadore. The family fired the firm in March.
