The jury will continue deliberations on Monday in the trial of a former Hull mom accused of murder in the fatal prescription drug overdose of her 4-year-old daughter. A jury on Friday ended the first day of deliberations without reaching a verdict.

Carolyn Riley is accused of overmedicating her daughter, Rebecca, on powerful drugs prescribed by a psychiatrist who diagnosed the girl with attention deficit hyperactivity disorder and bipolar disorder by the time she was 3. Her husband, Michael, faces a separate trial.

Defense lawyers say Rebecca Riley died of a fast-moving pneumonia, not a drug overdose.

The case reignited debate in the psychiatric community about whether young children can accurately be diagnosed with bipolar disorder and whether they should be given powerful drugs usually prescribed for adults.
