CHEYENNE, Wyo. (AP) — A Missouri couple has waived extradition to face first-degree murder charges in Wyoming in the deaths of their ex-spouses and two children more than 30 years ago.

Seventy-one-year-old Gerald Uden and 74-year-old Alice Uden of Chadwick, Mo., were jailed in Christian County in southwest Missouri.

Gerald Uden is accused of killing his ex-wife, Virginia Uden, and her two children, 12-year-old Richard Uden and 10-year-old Reagan Uden.

Virginia Uden and her children were last seen in Fremont County in central Wyoming in 1980.

Alice Uden is accused of killing her ex-husband, Ronald Holtz, who disappeared in 1974 or 1975. His remains recently were found in an abandoned mine in Laramie County.
