Stephen Forrest Hammer, 19, and Tanner Brooks Vanpelt, 18, were charged with felony counts of first-degree murder, aggravated robbery and other charges in Park County Circuit Court in the deaths of Ildiko Freitas, 40, and her parents, Janos Volgyesi, 69, and Hildegard Volgyesi, 70.
The courtroom was packed with friends and neighbors of the victims, and a heavy security presence was noticeable, the Billings (Mont.) Gazette reported.
No plea was offered by either suspect.
Although the hearing produced little information and Park County Attorney Bryan Skoric has not commented on whether the death penalty would be sought, charging documents provided new details on the slayings, the newspaper said, adding eight of the charges against each suspect carry the potential of a death penalty.
The documents said two people saw Freitas' dog running down the street Saturday morning, and returned the dog to its home, where they found Janos Volgyesi in a pool of blood on the garage floor, and Freitas, still alive, in the kitchen. Freitas was pronounced dead by emergency crews who arrived after a 911 call, and Hildegard Volgyesi was found at the bottom of basement stairs with a gunshot wound to the head.
Neighbors told police two men arrived at the home in a single car, entered the garage and left 20 minutes later, one man leaving in the Volgyesis' car. Both vehicles were pulled over by Wyoming Highway Patrol officers about an hour later, and both drivers were taken into custody, the documents said.
