Yup, a professional can use the recovered parts to trace down a make/model/year/color of auto, or @ least narrow down the population to a relatively small group of autos. Then, the investigator can begin his search. If there is enough evidence, this person can be tracked down - there is no question about it.

There is simply no way I would ever stop looking for this "driver". However, this type of research/work must be done ASAP if there is any chace of catching this sub-human. If anyone has an update to this story, please post.
