The FBI has determined a powdery substance found in a roll of quarters at a University of Texas dormitory was not ricin after initial state tests had indicated it was the potentially deadly poison, a spokesman said. The FBI tests did not identify the substance, but they came back negative for the poison, said San Antonio FBI spokesman Rene Salinas. "There were no proteins in there to indicate it was in fact ricin," Salinas said. He said it was unlikely further testing would be done.

Lee Browning, a researcher with a Texas seed company who has consulted with the FBI about ricin production, said a DNA analysis will show "if it's coming from South Carolina, Georgia, Florida or Texas."
