HAWKINS COUNTY, Tenn. (WBIR) -

A two-year investigation from the Hawkins County Sheriff's Department and the D.A.'s office is now over; now, the father of Alexa Linboom and his wife are in jail.

A lot of the girl's friends are now reliving what happened back on January 1, 2012.

According to the Sheriff's Department, 42-year-old Randall Lee Vaughn and his wife Mary Vaughn are charged with first degree murder, aggravated child neglect, and aggravated child abuse. They're both being held on $500,000 bonds in the Hawkins County Justice Center.

What we learned is back on January 1, New Year's Day, 2012, the young girl was brought to the emergency room at a local hospital. She was unresponsive at the time.

According to the D.A., the young girl was forced to drink grape soda and water -- forced as a form of punishment. The girl was taken to a Tri-Cities hospital -- where she died a couple of days later.

The young girl went to Surgoinsville Elementary School. Some of her friends say this news, thinking about it two years later, is still hard to hear. They're now just in the second grade.

"She was a nice friend and everything. And she played with me on the playground," said Hope Justice, Alexa's friend. "She swung, and we went down the slides, and played tag."

A WBIR crew stopped by the family's house in Surgoinsville earlier in the day Thursday. Nobody was home at the time, but there was a truck out front with young girl's name etched on the back glass. Neighbors say that Randall, the father, was a quiet man who kept to himself.

The couple will back in court April 30 for pre-trial motions.

The trial date is set for October 20.
