Authorities in Indiana say a 20-year-old woman beat her infant daughter to death earlier this year.

According to WRTV, the Monroe County Circuit Court secured an arrest warrant this week for Anna Prewitt-Byers of Nashville.

Indiana State Police officers took her into custody on Wednesday following an investigation that dates back to the 7-month-old girl’s death in April.

The suspect is expected to face criminal charges including battery resulting in the death of a person under 14 years of age and aggravated battery.

Prewitt-Byers transported the young victim to Indiana University Health Bloomington on April 18. The girl was admitted with multiple serious injuries.

The Brown County Democrat reported that she pleaded not guilty to the charges against her during a preliminary court appearance following her arrest.

As of the latest reports available, she remained behind bars at Monroe County Jail with bond set at $50,000 surety and $500 cash.

She initially told police her boyfriend was responsible for the injuries. Police agreed to her request for a polygraph test, but she reportedly failed it when she took it more than a week after the incident.

Prewitt-Byers’ boyfriend at the time, Michael Witham, was also arrested on unrelated drug charges but has vehemently denied any role in inflicting the fatal injuries.
