POWELL, Wyo. -

Two teens from Cody are being held in the killing of three family members in the tiny northwestern Wyoming town of Clark.
    
Sheriff Scott Steward says 19-year-old Stephen Hammer and 18-year-old Tanner Vanpelt were arrested Saturday after neighbors gave deputies a description of two men seen entering the house.
    
The neighbors also saw two vehicles speeding away, including a black Audi belonging to 40-year-old Ildiko Freitas, who owned the house with her husband.
    
Freitas and her parents, Janos and Hildegard Volgyessi, were fatally shot.
    
Hammer and Vanpelt are expected to be charged Tuesday when they make their first appearance in court.
    
Steward gave no indication of motive.
