10 Webster Ave. 1-2 Somerville, MA 02143 April 11, 1993 Todd Vaughan 215 Second St. Apt. 4 Jackson, MI 49201 Dear Todd, I am VERY concerned about the material I sent you in a recent package. I have enclosed a copy of the letter I had included with that material and marked the things which I sent you and need back. As I have stated before, you can keep anything I send you unless I ask for it back. I need back the original photos and negatives as soon as possible. I had hoped that you would bring them to Chicago. I need to make copies for other people. I also wanted you to make a blow-up or mark the area where I could make a blow-up of the Stoughton photo where you think Meyers sees evidence of a person near the fence. Is it the area I have marked with a square? I copied all the files for you onto 3-1/2" DD disks, IBM format. The photocopies are tests of the Rickerby. I may also try to get the negative to see if that would make it easier to get better quality photocopies. Also, the photocopies from ads in National Geographic and Parade do not come out too well, so you may want to try digging up some old copies to clip them out. I also need to remind you that I would really like to see your linear regression studies, even if they are in raw form. They may help to resolve the question of whether or not channel one had hold relays. Have you figured out what impact that would have on the assumptions about the power hum and "bell" sound frequency analysis if channel one had hold relays? Have you done any comparison of the frequencies in all the cross-talk messages? Is there anything we discussed in Chicago that you feel needs to be covered in more detail? Have I forgotten to copy anything you wanted? Feel free to ask for whatever you need. As always, W. Anthony Marsh
