The Sisseton Wahpeton Oyate of South Dakota is offering a $7,500 reward for information about a missing tribal member.

Andrew Lufkins, 23, also known as A.J. Lufkins, was last seen on April 7. He had been living with his grandfather.

"I've been staying there, hopefully waiting for a phone call but nothing," Carl Lufkins told KELO-TV last month.

Tribal, state and local authorities have joined the search for Lufkins but there haven't been any clues to his disappearance.
