Investigators say they still have no clue what happened to a Utah couple missing in Arizona. Jerry and Susan McFalls of West Jordan have not been heard from in more than two months.
The Mohave County Sheriff's Office in Arizona said in a statement yesterday that bullet casings found recently at the McFalls' second home were left there by a family friend who was target shooting.
A mattress cover with red spots on it also tested negative for blood.
Arizona investigators have classified the McFalls' disappearance as a missing persons case with suspicious circumstances.
