Useful traces of DNA on clothes, buried 16 years ago?
I doubt it, but let's hope they find what they are looking for!
"In fact, clothing is often the best source of evidence in a sexual assault case. Unlike the human body that continues to change as a result of biological needs and hygiene, crime scene evidence such as clothing is typically stable. Therefore, DNA evidence that is recovered from such a source is likely to be detectable for many years and perhaps even decades following a sexual assault."
The type of DNA they'll be hoping to find is semen.
