RIVERTON, Wyo. (AP) — A 20-year-old man charged in a double slaying in Hudson has pleaded guilty to two counts of second-degree murder.

The Associated Press reports Laziur Stephen Hanway Jr. of Ethete entered his pleas Thursday for the Nov. 15, 2011, stabbing deaths of 42-year-old Eric Clinton Likes and his girlfriend, 20-year-old Elva Charlotte Quiver, at Likes' home. Hanway also was accused of lighting the couple's home on fire two days after the killings.

Hanway, who is one of five people charged with killing the couple as part of a robbery plot, struck a plea deal with prosecutors that calls for two concurrent life terms on each count. His plea agreement is the fourth reached in the case.

Hanway is expected to be sentenced within 30 days.
