If and when Thomas Eric Duncan, the first patient diagnosed with Ebola in the U.S., returns to Liberia, the board of directors of the Liberia Airport Authority say they plan to prosecute him for lying on an airport health questionnaire.

Passengers leaving Liberia are asked whether they've had contact with anyone infected with the Ebola virus. Duncan's questionnaire, obtained by the The Associated Press, reveals that Duncan answered "No" to those questions, despite reports from neighbors who say Duncan assisted a sick pregnant woman who later died of Ebola. Though as AP notes, "her illness at the time was believed to be pregnancy-related."
