Mute testimony: The missing killer?

On night of murder of Mrs. Fannie McCue of Sept. 4th, 1904, I saw Dr. McCue go in Sam's house, and five or ten minutes later, I saw a boy or lad run fast out of the house down south Park Street to the city, I thought like Wm. McCue (white hat & dark clothes). I also saw same time four boys at the mailbox talking & smoking. I don't know the names of the young boys. –Neighbor Frank Massie's intriguing note, which was entered into the court record but unheralded in trial testimony
