Their mother, Carrie, was released from the hospital Friday, December 14.

Court documents show Litwin told deputies she was not on the phone at the time of the crash.

She later admitted to erasing text messages after the crash.

The Erath County District Attorney M. Alan Nash said in a statment, “It is important for the drivers of Erath County to be warned that local prosecutors and law enforcement view cell phone use that takes one’s eyes off the road, even for a few seconds, as reCKLESS. The term reckless is significant because the law provides that operating a motor vehicle in a reckless manner which causes death, bodily injury, or puts a child at risk, is criminal and will be treated that way.”

A GoFundMe account has been set up to help the Sackett family.
