premise: Fabio Ochoa Vásquez (born May 2, 1957) is a former leading member of the Medellín cocaine trafficking cartel, along with his older brothers Juan David and Jorge Luis. His role briefly made him a billionaire. After serving a brief prison term in Colombia, he was arrested and extradited to the US in 1999 and is serving a 30 year term in US federal prison.
hypothesis: Fabio is not the older brother of Juan David.
reason: Fabio was in the cartel with his older brothers Juan David and Jorge Luis, so he is not the elder one. The model just went by the phrase 'older brother' but assigned it to the wrong one.
