The father strangled Celeste first, wrapping her head with a blue Yankees blanket and covering her mouth and nose with his hands through the fabric. Bella was sitting next to her in the backseat the whole time, but didn't say anything, Watts said.
After Celeste stopped breathing, he dumped her body into an oil tank, feet first, locked the hatch, and walked back to his truck.
“Is the same thing gonna happen to me as Cece?” Watts recalled Bella asking softly when he returned.
That's when he said he grabbed the same blue blanket, put it around Bella's head, and "did the same thing."
“Daddy, no!” were the last words she said before dying, words he still hears whenever he shuts his eyes, Watts told investigators.
