CHEYENNE, Wyo. (AP) — Police suspect illegal drugs played a role in a shooting that has killed two people and seriously injured two others in Wyoming's capital city.

Cheyenne police on Tuesday identified those killed as 37-year-old Adrien Butler and 30-year-old Shaline Wymer, both of Cheyenne.

Two boys whose identities have not been released have life-threatening injuries.

Police spokesman Kevin Malatesta says previous calls to the home where the shooting occurred lead investigators to suspect a drug connection.

Police received a call of shots fired at the home at around 4:30 p.m. Monday. They say they arrested 25-year-old Andrew Weaver, of Cheyenne, in a nearby field a couple of hours later.
