Watch Live: Lindsay Clancy trial jury hears from Andrea Yates trial witness

Lindsay Clancy's murder trial resumed Friday in Massachusetts for what could be the final day of witness testimony. Forensic psychiatrist Dr. Phillip Resnick, a key witness in the Andrea Yates case after she killed her five children in Texas in 2001, took the stand to testify for Clancy's defense.

You can watch testimony when court is in session live on CBS News Boston in the embedded video or on YouTube .

Clancy, 36, has pleaded not guilty to first-degree murder in the deaths of her three children, 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan, in their Duxbury home on Jan. 24, 2023 .

There was only about 20 minutes of testimony on Thursday before court ended for the day. After jurors left, Plymouth Superior Court Judge William Sullivan worked through logistics with prosecutors Jennifer Sprague and Shanan Buckingham and defense attorney Kevin Reddington.

Reddington said Resnick will testify Friday via Zoom as the final defense witness, then he expects the prosecution to call three rebuttal witnesses. Judge Sullivan said if all testimony concludes Friday, closing arguments could be held Monday. If testimony needs to resume on Monday, closings would likely be held Tuesday.

Resnick testified for the defense in the 2006 Andrea Yates trial. She was found not guilty by reason of insanity. Resnick testified that Yates suffered from severe postpartum psychosis .

Resnick's testimony over Zoom was delayed by technical difficulties. He explained to the jury that he recently had surgery that prevented him from flying to Massachusetts for the trial.

Judge Sullivan said there would be a short break while the court works to fix the issue.

In Clancy's case, the prosecution alleges she planned the murders before faking a suicide attempt. Reddington has attempted to show that Clancy should not be held criminally responsible for the murders because she was overmedicated and suffering from postpartum psychosis .

If convicted of first-degree murder, Clancy faces life in prison without the possibility of parole. If found not criminally responsible for the deaths of her children, she will be sent to a state psychiatric hospital in Massachusetts.
