The Carmichael man accused of trying to kill his two children back in 2015, is set to be sentenced next month, after pleading guilty to the crimes on Thursday.
Sacramento Sheriff's Deputies say Charles Ewers used a mallet to repeatedly hit his kids.
Deputies say Ewers told them he had first given his children Ambien to make them drowsy, but that didn't work.
He then put them in a car rigged with exhaust hoses to murder the eight and ten-year-olds with carbon monoxide poisoning.
He too was in the car when deputies arrived at the house responding to a concerned call from the children's mother, his estranged wife.
Ewers could get 22 years to life in state prison when he's sentenced.
