PELLA (AP) — A Pella woman has pleaded guilty in the death of her 13-month-old daughter, who was left in a bathtub and drowned.

Pella police say 28-yearold Anna Nicole Sothman pleaded guilty Friday in Marion County Court to child endangerment causing death following a six week investigation of the death of Elaine Sothman. The conviction includes a penalty of no more than 50 years.

The investigation began after police responded June 20 to a report of an unresponsive child in Pella. She died June 23 at a Des Moines hospital.

An autopsy shows she drowned.

Investigators determined Anna Sothman put Elaine in a bathtub of running water and left her unsupervised for more than 30 minutes.

Anna Sothman was taken to the Marion County jail and will be sentenced later.
