A serial rapist is loose in central Texas, and he's targeting older women. Beginning with the rape of a 65-year-old woman in Yokum last January, at least eight sexual assaults or attempted sexual assaults, and four robberies or attempted robberies have been linked to the predator, dubbed the "Twilight Rapist" because most of the attacks happened around dawn. The victims have been women age 65 to 91. All of them live alone in towns with 6,000 residents or fewer, and one woman had more than $10,000 stolen. The attacks appear to have been planned—victims have had phone lines cut and porch lights unscrewed. Police have only a vague description of the suspect, a thin, young dark-skinned man between 5 1/2 and 6 feet tall, and so far, the DNA he's left behind hasn't matched anything in the state system.
