This site is dedicated to the potential victims and family members as a resource to try and sort out what has happened to their loved ones. A single coincidence occurs in many of the crimes that will be discussed, and that is the handwriting.

If you can tolerate the gum-smacking dribble from the distractors aka those that do not want this case solved, there is some good photographic, audio, and video evidence on Jack W. Tarrance, Jr. as promoted by Dennis Kaufman. Keep in mind we had a falling out, and working with someone most probably raised by the Zodiac Killer should explain his take on me once I refused to work with him.

This is where you can find my discussions on the evidence, and not so much on the person presenting it which helps to sift out the distractors and that waste your time.
