A forensic psychiatrist has testified in a murder trial, questioning the defendant's claim of postpartum psychosis. The defendant allegedly heard a voice that ordered her to harm her children. This voice was said to have started after a phone call from her husband.

The psychiatrist, who works with the FBI, conducted video interviews with the defendant earlier this year. He shared details from these interviews during his testimony.

Further information about the trial and testimony is available from the source, including details about the defendant's statements and the events surrounding the incident.
