Police say they seized more than 30 firearms, along with body armour, numerous illegal magazines and many rounds of ammunition from a home where the young man now charged with three homicides had been staying.

Mickell Clayton Bailey, 19, faces two charges of first-degree murder and one charge of second-degree murder.

RCMP on Monday said autopsies completed by the Edmonton medical examiner's office confirm that Daniel Miller, 46, Roxanne Berube, 36, and her daughter, Jazmine Lyon, 16, were all homicide victims. They did not release any details about how the three were killed.

The bodies were discovered on Sunday, Nov. 29, at a rural home near Edson.

Bailey's first court appearance is scheduled for Dec. 15 in provincial court in Edson.
