It appears that, about the last of October, one Gregory Summerfield, an old man nearly seventy years of age, in company with Parker, took passage for Chicago, via the Pacific Railroad, and about the middle of the afternoon reached the neighborhood of Cape Horn, in this county. Nothing of any special importance seems to have attracted the attention of any of the passengers toward these persons until a few moments before passing the dangerous curve in the track, overlooking the North Fork of the American River, at the place called Cape Horn. As our readers are aware, the road at this point skirts a precipice, with rocky perpendicular sides, extending to the bed of the stream, nearly seventeen hundred feet below. Before passing the curve, Parker was heard to comment upon the sublimity of the scenery they were approaching, and finally requested the old man to leave the car and stand upon the open platform, in order to obtain a better view of the tremendous chasm and the mountains just beyond. The two men left the car, and a moment afterward a cry of horror was heard by all the passengers, and the old man was observed to fall at least one thousand feet upon the crags below. The train was stopped for a few moments, but, fearful of a collision if any considerable length of time should be lost in an unavailing search for the mangled remains, it soon moved on again, and proceeded as swiftly as possible to the next station. There the miscreant Parker was arrested, and conveyed to the office of the nearest justice of the peace for examination. We understand that he refused to give any detailed account of the transaction, only that "the deceased either fell or was thrown from the moving train." The examination was postponed until the arrival of Parker's counsel, O'Connell & Kilpatrick, of Grass Valley, and after they reached Cape Horn not a single word could be extracted from the prisoner. It is said that the inquisition was a mere farce; there being no witnesses present except one lady passenger, who, with commendable spirit, volunteered to lay over one day, to give in her testimony. We also learn that, after the trial, the justice, together with the prisoner and his counsel, were closeted in secret session for more than two hours; at the expiration of which time the judge resumed his seat upon the bench, and discharged the prisoner! Now, we have no desire to do injustice toward any of the parties to this singular transaction, much less to arm public sentiment against an innocent man. But we do affirm that there is, there must be, some profound mystery at the bottom of this affair, and we shall do our utmost to fathom the secret.
