Meier noted that Patrick is 'not seeking to close the courtroom.''Mr. Clancy seeks a narrowly circumscribed order limiting the recording, display, and disclosure by the media (or any other persons) of certain graphic and sensational items of evidence related to his three young children, which, if disseminated, would only serve to perpetuate the already severe emotional harm to Mr. Clancy and his family,' he wrote.The judge granted his request, so the evidence will be seen and heard in the court room, but not displayed on the live stream.19:44Inside new life of Lindsay Clancy's husband and fertility doctor wife: Family reveals touching texts, intimate wedding details and happy photos... as ex stands trial for murder of their three childrenAs a Massachusetts courtroom prepares to grapple with one of America's most heartbreaking family tragedies, the father at the center of the case has quietly built a new life hundreds of miles away.When the murder trial of former labor and delivery nurse Lindsay Clancy begins next week, jurors will hear evidence about the deaths of her three young children, a case that has sparked fierce debate over postpartum mental illness and criminal responsibility.But while Lindsay, 35, prepares to fight for her freedom on an insanity defense, the Daily Mail can exclusively reveal that her former husband, Patrick Clancy, 38, has found love again and started over in New York City.
