A four-year-old girl died after she climbed into a washing machine and her little brother switched it on.
Kayley Ishii was inside the front-loader when her 15-month-old brother managed to start it.
A sheriff's spokesman in Orange County, California said the machine's controls were 20 inches from the floor and the start switch was a simple push button.
The girl was in the water-filled, tumbling machine for at least two minutes before her mother found her. Her death was ruled as accidental.
Investigators said the mother could not explain why Kayley climbed inside the machine.
"They don't know if they were playing or what," said the spokesman.
