The Tanacu exorcism was a case in which Maricica Irina Cornici, an allegedly mentally ill nun at the Romanian Orthodox Church monastery of Tanacu in Vaslui County, Romania, was ruled to be killed during an exorcism led by priest Daniel Petre Corogeanu and four Orthodox Christian nuns who were a part of the Order of the Holy Trinity. The case was widely publicized in the Romanian media and following a lengthy trial, the priest was sentenced on appeal to 7 years, one nun to 6 years and the other three nuns to 5 years; however, many of Tanacu's residents, including Cornici's brother, believed her to have suffered from demonic possession. The coroner Dan Gheorghiu maintained that the nun's cause of death was due to an overdose of adrenaline given in the ambulance.
