Yes, and also, the vehicle showed no signs of having been wiped down. This suggests that whoever drove it either wore gloves (odd things to have about you at the end of July); or, wasn't worried about having to explain the presence of his fingerprints inside the car, because they could be innocently explained.
Which says someone she knew, or someone who would have had a reason to have previously been inside or at the wheel of her car. Friends, workmates, work contacts.
A big issue with so much of what is posted on this thread is the clearly apparent lack of understanding of the investigation process, police procedures and powers. Incorrect assumptions are consistently being made, which only serve to mis-inform others.
In this instance we have comment on fingerprint evidence.
1. Fingerprints are most successfully lifted from clean, smooth, hard, non-porous surfaces.
2. Clean, dry glass is invariably the perfect medium.
3. Plastic with a graining effect, which was often found in vehicles, circa 1986, is not a surface conducive to obtaining fingerprint evidence.
4. High traffic areas will often have multiple fingerprints overlain and consequently smudged. Even if the surface is a suitable medium then the likelihood of an individual print, that can be lifted and provide sufficient distinguishing features, is minimal.
5. Any fingerprint evidence from a publicly accessible area, including unlocked vehicles, is evidentially contaminated.
6. Fingerprint procedures can identify if marks left are from a gloved finger/palm if it partially overlays surrounding fingerprint marks.
7. It is much more likely to be the case that either no suitable fingerprint evidence could be recovered or that those recovered were satisfactorily eliminated.
8. It would be wrong to assume from any absence of suspect fingerprints, if indeed the offender had contact with the vehicle, that they either wore gloves or 'wiped down' the vehicle. It is far more nuanced than that.
9. Fingerprints can be be aged, therefore their relevance to the investigation can be established.
