John B. Arum, the 49-year-old son of Hall of Fame boxing promoter Bob Arum, has gone missing while hiking in North Cascades National Park in Washington state, about 125 miles northeast of Seattle, near the Canadian border. Bob Arum, 78, flew to Seattle from Los Angeles on Tuesday after learning of the news and was planning to drive to the park Wednesday to await news about his son.
A tent with a pair of sunglasses and binoculars belonging to John Arum were located in the park. Visibility has been poor, preventing an air search up to this point.
Bob Arum was notified of his son's disappearance shortly before a news conference at the Beverly Hills Hotel in Los Angeles to promote the Nov. 13 fight between Manny Pacquiao and Antonio Margarito. Bob Arum conducted the news conference Tuesday, but will skip the final legs of the promotional tour Wednesday in New York and Thursday in Texas.
An experienced hiker, John Arum is an attorney who specializes in environmental law. Arum, who is with the Seattle law firm of Ziontz, Chestnut, Varnell, Berley & Slonim, graduated from Reed College in Oregon and the University of Washington Law School.
