Detective Scott Roberts

She had been abducted from a parking lot in Madison and sexually assaulted and killed. And he was convicted of that in the late 70s and sentenced to life here in prison in Wisconsin. And after that time, the late 90s, early 2000s, he was convicted of a double homicide of some hitchhikers in the Los Angeles area. And then, again, in the early 2000s, he was convicted of homicide in Tucson, Arizona.

So he definitely was in the area, and the records from the jail back then that they had were on microfilm, and they were difficult to read. Investigators believed it was possible that he was in jail at the time of this case, but they're not certain because of the quality of the records. And when they talked with or attempted to talk with Zamestilla, he said, well, no, I wasn't in custody.

And they basically said, well, we need to know some details and he was not willing to provide them.

They did identify some sperm cells on the swabs, but at the time, there wasn't enough genetic material present to develop a full profile for the male, and certainly not a profile that would be suitable for entry into a database like CODIS.
