A mother accused of killing her 4-year-old daughter by overmedicating her with powerful prescription drugs is to go on trial on a murder charge.
Testimony in Carolyn Riley's trial is scheduled to begin Tuesday in Brockton Superior Court.
Riley and her husband, Michael, are accused of overusing drugs Rebecca Riley had been prescribed for attention deficit hyperactivity disorder and bipolar disorder.
The Rileys deny the charges and say they were following the advice of their daughter's psychiatrist. They say their girl died of pneumonia, not a drug overdose.
The husband and wife will have separate trials. No date has been set yet for Michael Riley's trial.
