LANDER, Wyo. (AP) — The FBI is offering a reward of up to $10,000 for information about a July 2007 murder on the Wind River Indian Reservation in Wyoming.

The agency is seeking information about whoever is responsible for the death of 50-year-old Kim Allen Morin of St. Michael, North Dakota, and help in locating the .22 caliber Marlin rifle officials believe was used in the killing.

Morin was last seen in the Fort Washakie area the morning of July 27, 2007. He planned to travel to Lander with his friend's son, but there's no indication he ever arrived. Morin's remains were found in October 2007 about eight miles north of Fort Washakie.

The agency has a person of interest but the case is still being investigated.

Anyone with information is asked to call the FBI in Lander at 307-349-6458.
