The individual from the 1989 crime scene is the victim in the current investigation

You: It seems like the DNA pattern from the 1989 crime scene matches the current victim’s, so could the individual from the 1989 crime scene be the victim in the current investigation?

Eric: That would suggest the same person is connected, meaning the 1989 individual and the current victim are the same.

Dr. Greene: It's good to explore possibilities, but let's take a closer look at what the RFLP results are actually telling us. Are the patterns from the victim and the 1989 crime scene identical? They seem quite different to me. For example, look at the largest bands at the top of the gel from the crime scene. Those are missing from the victim’s pattern.

You: I see what you mean, Dr. Greene.

Dr. Greene: Let's reevaluate what the RFLP patterns suggest.
