RIVERTON, Wyo. (AP) — Investigators say a lighter helped lead to the arrest of a teen in a double slaying in Hudson.

Nineteen-year-old Laziur Hanway of Ethete (EE'-tha-tee) was arrested last week. He's accused of robbing and stabbing 19-year-old Elva Quiver and 43-year-old Erik Likes and then setting fire to Likes' home in November.

The Ranger (http://bit.ly/zN9Eqp ) reported Sunday that, according court documents, a lighter found near the trailer had the blood of both Likes' and another man on it. Blood was also found inside Likes' pickup.

Investigators collected DNA samples from several people, including Hanway, and found that his sample matched the DNA found in the blood. Hanway's father was also tested.

Authorities say Likes was a stonemason and Hanway had worked for him.

Hanway is set to have a preliminary hearing on Wednesday.
