look for the suspect and keep his eye on the composite at the same time to try to find someone that looked just like that. >> but someone did look just like that -- doug desilva. desilva lived 100 miles away, but his ex-wife and daughter both lived in the same mobile home park as kaye robinson. a year earlier, he was the suspect in the murder of a 16-year-old girl at a nearby high school. police brought desilva in for questioning. in the middle of the interrogation, he did something very odd. he asked for a job application because he said he wanted to become a state trooper. >> we thought maybe he might even be taunting us at that point. we were very suspicious of that. >> police put together a photo lineup, and kaye robinson identified desilva as the man who attacked her. >> it was more like an internal reaction.
