“We will coordinate with the courts on her arraignment on her indictment,” Simpson told News Center 7′s John Bedell.

Earlier court hearings have been delayed after Heidi was transported to a mental health facility last week. Her defense attorney asked a Preble County judge to delay her initial appearance in November after she was taken to a Cincinnati-based mental health facility.

Heidi is accused of drowning Alice Nov. 15 inside a house on East Somers Street.

A police report obtained through a News Center 7 public records request stated Heidi told police that she went behind her grandmother while she was doing dishes and she held her head in the sink “until she stopped blowing bubbles.”

Heidi told police she wasn’t sure if her grandmother was dead yet so she filled up the bathtub and held Alice under for 15 minutes until she stopped breathing and left her in the bathtub.

Heidi then walked from the apartment
