Oklahoma City police have released the identities of the five people killed Wednesday in a house fire at 2812 Dorchester Drive. The mother was 28-year-old Jeanine Bonnet. Her four children who died were 8-year-old Natalie Leon, 7-year-old Samantha Leon, 5-year-old Matthew Leon and 3-year-old Kara Leon. Investigators say the fire was caused by a space heater in the living room that caught a piece of furniture on fire. 39-year-old Brian Poletto was taken to a hospital in critical condition. A seventh person escaped the burning house.
