Madrid , Spain ( CNN ) -- The final autopsy report on a San Diego State exchange student whose body was pulled from a Madrid river last March indicates an accidental drowning death with no signs of external violence , a Spanish court official said on Tuesday . The student , Austin Taylor Bice , 22 , was studying a semester of business courses at the University of Carlos III in Madrid when he went missing after a night out with friends . He was last seen outside a nightclub on the banks of Madrid 's Manzanares River . Ten days later , on March 8 , police pulled his body from the river . `` There was nothing found in the body that would indicate external factors in the death . There were no wounds on the body , '' said the official from Madrid 's Superior Justice Tribunal . He spoke on the customary condition of anonymity . He said the autopsy also showed a `` high level '' of alcohol in the blood . A Madrid judge has kept the case , which is confidential by law , open for further investigation . There was no immediate word on when it might be closed definitively , the official said . After his disappearance , Bice 's friends quickly organized a campaign to put up posters of him around Madrid , which read `` Missing . Austin Taylor Bice . U.S. citizen , 22 , 1.95 meters tall and 100 kilograms '' ( 6 feet , 5 inches and 220 pounds ) , and Spanish and U.S. media reported on the search . Bice 's father Larry , an accountant , rushed to Madrid from San Diego to search for his son and met several times with Spanish and U.S. authorities . The family hired private investigators , at first to try to find the student , and later , after his body was recovered , to try to determine what happened , the elder Bice told CNN . At the time of the search , a family member told CNN in Madrid that contrary to initial reports , Bice was not refused entry to the nightclub by doormen and was not drunk , although `` he had a few beers . '' Instead , he just decided to go home . On March 8 , when police recovered the body , an initial visual inspection did not indicate any signs of violence , Madrid officials said at the time . The U.S.-based Institute of International Education said that in 2007 , Spain was the third most popular destination worldwide for Americans studying abroad , after the United Kingdom and Italy . It said there were about 17,000 American students in Spain . The University of Carlos III , where Bice was studying , has 18,000 students , of whom 1,500 are from abroad , including about 220 Americans , Carlos Lopez Terradas , the school 's head of international relations , told CNN in early March .
