Relatives have asked the public for help in finding a 36-year-old man feared missing in the United States, over two months after they last heard from him.Sharon Harush set out alone for a trip to the United States in early March with plans to visit sites from coast to coast. His brother, Avi Harush, said that initially Sharon had spoken to the family regularly and that in April he had bought a laptop to keep in touch through Skype and e-mail.Sharon Harush’s family last spoke to him on May 8 on Skype while he was touring Los Angeles. Avi Harush said that periodically throughout the trip, his brother would withdraw $400 from his Israeli bank account to pay for expenses, and that the last recorded withdrawal was $400 from an ATM in Las Vegas on April 4.“He is a very quiet, normative person who liked to keep to himself for the most part. It is not at all like him to cut off communication or to just disappear like this,” said Avi Harush.He said the family had contacted the Israeli authorities in the US, including the Israel Police contingent, as well as American law enforcement officials, US immigration officials, and Interpol. No one has been able to find any trace of the missing man.Details issued by the family list Sharon Harush as 5 feet, 7 inches, 187 pounds, with a shaved head and a light complexion.
