CASPER, Wyo. (AP) — A federal judge will consider a request from an airplane preservation group to dismiss a lawsuit filed by a Wyoming man who claims the group found the wreckage of Amelia Earhart's airplane a few years ago in the South Pacific but kept the discovery secret.

U.S. District Judge Scott Skavdahl has set a hearing in Casper for Tuesday morning.

Timothy Mellon, son of the late philanthropist Paul Mellon, in June sued the International Group for Historic Aircraft Recovery of Delaware and its executive director, Richard E. Gillespie.

The group and Gillespie deny Mellon's claim that they found the wreckage of Earhart's plane. She disappeared over the South Pacific in 1937.

Mellon, of Riverside, Wyo., says the group solicited $1 million from him last year for the Earhart search.
