(CNN) -- A Tennessee couple faces murder charges for allegedly punishing the man's 5-year-old daughter by making her gulp excessive amounts of water and grape soda, leading to her death, authorities said.
Alexa Linboom was forced to guzzle the fluids after she took "one or two grape drinks" that belonged to her stepmother, District Attorney Berkley Bell told CNN affiliate WJHL.
"She was allegedly force-fed so much liquid that it caused the sodium level in her body to go down and caused her brain to swell," he said.
In addition to drinking more than 2 liters of fluids in about two hours, she also suffered other forms of punishment, Bell told the affiliate. He did not get into specifics.
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.
