FORT DAVIS, Texas: An aerial search turned up no sign of the last remaining Republic of Texas fugitive, tentatively identified as 21-year-old Richard Keyes. Department of Public Safety officials have scaled back their ground search for Keyes out of fear that the Davis Mountains' rough terrain would make it impossible to rescue any injured personnel. Authorities have still not given a positive identification for the fugitive killed Monday during a brief gunbattle, saying only that he is a "middle-aged white male." That suggests the dead man is fugitive Mike Matson, a 48-year-old resident of California who served as a bodyguard for Republic of Texas Ambassador Rick McLaren. Of the two fugitives, only Keyes was wanted by authorities on charges of aggravated kidnapping and organized criminal activity.
