Deleon graduated from a San Antonio high school in May 1981. Six days later, she went to a nightclub and vanished.
Her body with gunshot wounds was found along Interstate 35 outside New Braunfels in June 1984, but authorities didn't realize who she was at the time. Her identity could not be confirmed.
More recent testing from Deleon's body uncovered DNA from someone else.
“Eventually they work with a genealogist and similar to what people see in their family trees,” said Ray, a former Texas Ranger. “ I had a couple of key persons of interest through that testing and then through that we narrowed down to the one person to focus.”
West is free on $125,000 bond. A statement from the Texas Department of Public Safety says a grand jury will consider whether or not to indict him.
