From Plymouth, Mass.: A trial is underway for a mother accused of killing her three children. The defendant, a former nurse, acknowledges her role in the deaths but her attorney claims a psychological condition was a factor. Prosecutors argue she was aware of her actions.

The jury has been deliberating for several days and has indicated they are having trouble reaching a decision. Further details about the case and the trial are available. The jury's inability to agree on a verdict raises the possibility of a mistrial.

The case has drawn significant attention, with many people following the proceedings.
