CHEYENNE, Wyo. (AP) — Jurors have found a 75-year-old Missouri woman guilty of second-degree murder in the shooting death of her husband in Wyoming almost 40 years ago.

The jury in Cheyenne deliberated for about 13 hours before delivering the verdict Thursday in the case of Alice Uden.

Uden had testified she shot 24-year-old Ronald Holtz in the back of the head sometime in late 1974 or early 1975. She said she shot him just as he was about to attack her 2-year-old daughter in her crib. Prosecutors alleged Uden killed Holtz as he slept.

Investigators recovered Holtz's remains last summer from an abandoned mine shaft. Police arrested Uden and her current husband, 71-year-old Gerald Uden, in Missouri in September.

Gerald Uden has pleaded guilty to shooting his ex-wife and her two children in central Wyoming in 1980. Prosecutors haven't linked the two cases.
