Alicia Graham died from progressive thallium poisoning rather than terminal cancer, according to a legal complaint filed by her family against her husband, Juan de Bedout.
The document, which is now in the hands of the Fiscalía, details that Graham was allegedly intoxicated systematically while her death was originally categorized as natural. Fabio Humar, defense lawyer for Juan de Bedout, spoke with Caracol Radio regarding the ongoing legal situation.
“Estaremos atentos a los llamados que haga la justicia para esclarecer lo que corresponda y, desde luego, he recibido instrucciones de mi cliente, Juan de Bedout, para ofrecer toda la información que la Fiscalía requiera,” said Fabio Humar, attorney for Juan de Bedout, according to eltiempo.com.
Evidence Submitted to Investigators
Family members submitted evidentiary materials to prosecutors through their attorney, David Espinosa Acuña. The files include documents, audio recordings, personal conversations, and a medical test result.
An August 3, 2021 urine test belonging to Graham registered 672.9 micrograms of thallium per liter, according to the legal filing. Investigators also said that De Bedout allegedly asked to change a medical specialist after the attending physician wanted to pursue the thallium theory.
Extradition Proceedings for Zulma Guzmán
The investigation intersects with a separate criminal case involving Zulma Guzmán Castro that began in April 2025. Two minors aged 13 and 14 died in Bogotá after eating chocolate-covered raspberries contaminated with thallium, while two other individuals survived the poisoning.
The food items had arrived at the De Bedout family residence via a delivery driver the day before the incident.
Authorities identified Guzmán Castro as the primary suspect who allegedly organized the fruit shipment following the breakup of a romantic relationship with Juan de Bedout.
Guzmán left Colombia and police arrested her in London in December 2025, where she remains pending extradition. Prosecutors attempted to advance with charges of aggravated homicide and attempted homicide in November 2026, but the virtual hearing stalled because Guzmán failed to connect from London.
