By Dan Rafael ESPN.com Archive Top Rank promoter Bob Arum's son has been reported missing, forcing Arum to leave the three-city press tour that kicked off in Los Angeles on Tuesday to promote the Nov. 13 Manny Pacquiao-Antonio Margarito junior middleweight title bout. John Arum, 49, was reported missing Sunday after hiking in mountains north of Seattle, Top Rank spokesman Lee Samuels said. "We got a call today that he had gone hiking and is missing, so Bob told the staff this morning that he would leave the tour and take a flight to Seattle," Samuels said. "Bob and his wife, Lovee, have left the tour and proceeded to Seattle." Arum could not be reached for comment, but he told the Los Angeles Times before leaving for Seattle, "They've got search parties looking for him right now." The tour continues on Wednesday in New York and then will move to Dallas on Thursday for two days. Top Rank president Todd duBoef, Arum's stepson, will run the press conferences in place of Arum. The fight will take place at Cowboys Stadium in Arlington, Texas, where Pacquiao will fight for the second consecutive bout. He outpointed Joshua Clottey there on March 13 in a welterweight title bout.
