The jurors in the Lindsay Clancy trial said Tuesday they could not agree.

Judge William Sullivan told them to keep talking.

The jury is in its fourth day of talks.

Many people are watching this case.

Clancy was a nurse.

She helped women have babies.

She does not say no to hurting her three children.

She says she is not guilty.

She says she was not responsible.

Her lawyers say postpartum psychosis made her do it.

Prosecutors say she knew what she did.

The jury can say she is guilty of murder.

Or they can say she is guilty of manslaughter.

Or they can say she is not guilty.

If she is guilty, she could go to prison for life.

If she is not guilty, a judge can still send her to a mental hospital.

This can happen if she is dangerous.

If the jury cannot agree, the trial can end.

Then prosecutors can decide to try her again.

Clancy killed Cora, Dawson, and Callan.

They were 5, 3, and 8 months old.

She used exercise bands in her basement.

Then she jumped from a window.

Now she cannot move her legs.

Her husband is Patrick Clancy.

He talked in court.

He says he forgives her.

The trial talks about mothers' mental health after having a baby.
