Christina Lee Ward, 26, and two of her children, Dalton Ray James Ward, 4, Mackenzie Brooke Ward, 2, were killed Wednesday morning in an apartment fire in Logan.
A family friend who was staying overnight in the apartment escaped. The children's father was at work and two siblings were already at school.
The blaze appeared to have started in a kitchen wall near the oven, and fire investigators were considering bad wiring as the likely cause, Logan Police Capt. James Geier said.
Fire officials said the family's apartment had smoke alarms but no batteries.
The apartment was destroyed, and the four-plex had significant damage. Four people from another unit in the complex escaped, and the other two apartments were unoccupied.
Wednesday afternoon, Arista Hamilton, 12, was killed in a fire at her family's trailer.
Firefighters found the girl inside the burning trailer and dragged her out. She was taken to Logan Regional Hospital, where she later was pronounced dead. She was the only person in the trailer when it started fire.
A preliminary report by the state fire marshal's office lists the cause as accidental, said Smithfield Police Chief John McCoy. However, the exact cause has not been released.
