Just as a by-the-by factlet (OT .. forgive me, but I'm like a shark in the water with these old stories..) there was a horrendous murder connected to the Sammis property - I found it by following a link to Parsons stuff.. and of course, I can't find it again now I have time to write about it.
Anyhow. In Huntington, at some time prior to Alice's murder, a gentleman in his 30's decided to court a much younger girl, just out of high school. The whole town was in an uproar about it, but the man and the girl kept meeting in secret.
So one night, when he thinks he's meeting the girl and sees a lantern-light signal in the dark, the man gets jumped by a gang of masked men who beat him savagely and tar and feather him, using hot tar.
Later, a pair of tarred and feathered legs were found - the rest of the man's body never was located. Members of the Sammis family were rumoured to be involved but nobody had any proof. Many of those who'd been accused left the area afterwards. The murder is still unsolved - so there, we have another cold case.
Ehhh - here's the link!
