Fire possibly caused by a wood-burning stove swept through a rural home Sunday, killing five people, two of them young children, authorities said.
The fire broke out at about 7:30 a.m. and engulfed the mobile home on an isolated plot of land 10 miles south of Sierra Vista in southeastern Arizona.
The cause of the blaze, which was not immediately determined, is under investigation.
Carol Capas, spokeswoman for the Cochise County Sheriff's Department, identified two of the victims as Lisa Peters, 20, and her brother, Dirk Peters, 18. Also killed were Peters' 20-year-old girlfriend and her two children, ages 1 and 3, Ms. Capas said. Their names were not released.
The Peters' parents, Glen, 68, and Dora, 46, suffered minor cuts and smoke inhalation, and were taken to a hospital, she said.
