Marie Robards

Dorothy Marie Robards Strauch (born July 10, 1976) is an American woman, known for the poisoning murder of her father, Steven Robards, in 1993, when she was aged 16, in Fort Worth, Texas.

Crime
Marie stole barium acetate from her high school chemistry class and laced her father's tacos with a lethal dose. The trial received media attention since she was a promising student, and patricide is a rare crime more commonly committed by men.

Discovery and conviction
Steven Robards’ death was ruled a heart attack initially. Over a year after his death, Marie confessed to a close friend, Stacey High. Her friend then disclosed her information to law enforcement. The medical examiner’s office used a gas chromatography–mass spectrometry machine to examine his tissue samples and detected the highly soluble metallic compound. She confessed, telling police she wished to live with her mother. She pled not guilty, explaining her intent was to make her father ill.

Marie Robards was convicted of murder in a 1995 trial and sentenced to 27 years in prison. She was released on parole in 2003. She is believed to now be living under a new identity.

The crime was an inspiration for Megan Abbott's 2018 novel Give Me Your Hand, and was covered in episodes of Forensic Files (Season 6, episode 5 (2001)), Redrum (Season 2, episode 17 (2014)), and Deadly Women (Season 6, episode 2 (2012). it was also the subject of Morbid: A True Crime Podcast, episode 552 in March 2024.
