A Gwinnett County mother pleaded guilty Tuesday to involuntary manslaughter in connection with her infant daughter’s death, Channel 2 Action News reported.

Lauren Fristed was sentenced to 20 years in prison with 10 years in confinement, the news station reported. She was charged with involuntary manslaughter and reckless conduct.

Fristed’s 10-week-old daughter Nevaeh died in March 2015 after police said Fristed and her husband Herbert “George” Landell fed the baby breast milk diluted with water.

The couple took the baby to a hospital, but she was dead when they arrived, the Atlanta Journal-Constitution previously reported. Investigators believe Nevaeh wasn't properly clothed or fed and often had poor hygiene.

Landell’s trial is scheduled to start next week, Channel 2 reported. He is facing murder charges.
