According to The Tennessean, Randall Lee Vaughn, 41, and Mary Lavonne Vaughn, 58, were both sentenced Monday. Randall was the father of the little girl, Alexa Linboom, and Mary was her step-mother.
Alexa was forced to guzzle 2.5 liters of soda and water over a one to two-hour period after she took “one or two grape drinks” that belonged to her stepmother, District Attorney Berkley Bell previously told CNN affiliate WJHL.
The child became unresponsive, and the pair drove her to the hospital on New Year’s Day in 2012. Two days later, she was declared brain-dead and removed from life support. A two-year investigation determined her death was a homicide as a result of acute fluid/water intoxication.
