The whole thing about "waiting for DNA comparison" has me concerned. Several years ago, the city I live in experienced the vicious, high-profile murder of Brianna Denison. Semen samples taken from her body needed to be run through the system, but budgetary concerns had created a long backlog of DNA to be ran. The Denison family is very wealthy, so they donated some of their own money to work through the backlog, and many people in the community donated as well.
I really hope that isn't the case here. 25 years without a name is a terrible injustice.
I can't help but wonder where this woman's fetus is. Seems hunting down paternal DNA might be an option, if they for any reason kept the fetus. Just thinking out loud. If they could figure out who the father was, they might be able to figure out who the killer was.
