Judith Mae Andersen update
A little more research in the Judith Mae Andersen case has unearthed some interesting facts about the bucket used to dispose of her head and other remains.
Recall that Chicago police officials said the bucket was so rare that they couldn't find another one to show prospective witnesses. There's a good reason: En-Ar-Co motor oil was sold in Canada.
A website I found through Google Canada provided the following information:
This style of bucket was used from about 1939 (or the late 1940s) to 1952.
Here's the bucket from the killing:
And here are some modern photos. Note that the buckets are bright, industrial yellow (easier to spot in Lake Michigan than, for example, a black bucket):
I've e-mailed the two collectors to see if I can get a better picture.
