 In 1998 the ARPT group led by Nicholas Reeves began exploring in the area of Tutankhamun's tomb, based on two anomalies found during a sonar sounding in 1976.During the dig two undisturbed seals of the 20th dynasty scribe Wen-nefer, a well-known person whose seal has been found on many Valley tombs, were discovered.A radar scan in 2000 produced evidence of two empty chambers, but the work was halted pending an investigation into the theft of antiquities.
