The sighting comes during a particularly emotional period for Patrick, whose former wife is facing three counts of first-degree murder in connection with the deaths of their three children — Cora, Dawson and Callan — at the family’s Duxbury, Massachusetts, home in January 2023.

As we previously reported … Lindsay has pleaded not guilty; however, she acknowledges killing the children. Her defense argues she was not criminally responsible because she was suffering from severe postpartum psychosis and other serious mental-health problems at the time.

During the trial, the prosecution has presented evidence concerning Lindsay’s behavior and internet activity before the deaths, and the defense has focused heavily on her deteriorating mental state and attempts to obtain psychiatric help.

Patrick has already taken the witness stand, describing the devastating discovery of his children and his call to 911.

His testimony has been among the most closely watched portions of the proceedings.

The trial has also highlighted the family’s complicated history in the years leading up to the deaths … including Lindsay’s mental-health struggles and the efforts of relatives and medical professionals to help her.
