A search for a missing hiker in Joshua Tree National Park will intensify tomorrow. Officials say the number of rangers and sheriff´s volunteers looking for 60-year-old Marvin Matsumoto of San Jose will double to about 150 through Sunday. A National Park Service spokeswoman says some trails will be closed to contain the area but most of the park will remain open during the search. Matsumoto was hiking with his 16-year-old son Monday when the two split up near Barker Dam on a one-mile loop trail. The elder Matsumoto did not arrive at the pair´s prearranged meeting place.
Matsumoto was wearing jeans and a T-shirt when he disappeared. He has been described as an experienced hiker, but his family says he takes medicine for blood pressure and cholesterol level.
