Episode 151: Captain William J. Costello and The Smiling Widow

from Evil Everywhere: A True Crime and Horror Podcast · host Dark Energy Productions, LLC

What would you do in the face of murder charges? Most people would be frantic, pleading their innocence, and very anxious of what is to come. But that was not the case for Jessie Costello in 1933. That February, she found her husband, Captain William J. Costello, dead on the floor of their home in Peabody, MA. At the request of close friends, an autopsy was performed which found poison, despite the body having already been embalmed.  It was confirmed the poison had been sold to Mrs. Costello the night before the captain’s death, but Mrs. Costello claimed she had been using it simply as a cleaning agent. With the evidence piling up, Jessie Costello was charged with the murder of her husband. As the trial began, the media and community became obsessed with this woman. Smiling, calm, entrancing all those around her. She would receive hundreds of love letters daily from men all over the country, pose for photos as she entered the courtroom and would smile all throughout the court proceedings. But would her charm be enough to convince the jury of all men of her innocence?   Sources: “Justice and Jessie Costello” by Undine on Strange Company (https://strangeco.blogspot.com/2014/05/justice-and-jessie-costello.html) “Widow’s Illness Laid to Ordeal: Mrs. Costello’s Condition will Prevent Questioning Today” by Alfred J.
