Martin Kenkouwsky, alias Louis Kettler, the murderer of Mrs. Mina Muller, was captured on the night of May 19th, 1881, by Policemen Morris Fitzgerald and Richard Tregonning of the Thirty-seventh street police station, as he was walking in Thirty-sixth street, near Tenth Avenue, New York City. The clue which led to his detection was discovered and followed out almost to the end by Gustavus A. Seide, a reporter for a Jersey City newspaper, and compares, as a piece of amateur detective work, with the detection of Chastine Cox, the murderer of Mrs. Hull. Seide recognized that there was a flaw in the theory that the alleged murderer had gone to Europe in the Amerique. There was no certainty that the baggage which was taken from Sherrer’s house on the day the steamer sailed was delivered at the pier of the French line, nor was there positive evidence that Kettler himself had been seen on the pier that morning. Superintendent West of the French pier said that on the day the Amerique sailed, a man answering somewhat Kettler’s description had applied to him for a ticket, and he had referred him to the purser. Baggage corresponding to what Kettler was supposed to have taken with him the Superintendent had not seen on the pier. Seide came over to New York early Thursday morning, May 19th, and proceeded at once to look for the man who was supposed to have taken Kettler’s baggage from Scherrer’s Hotel to the pier. Scherrer had seen the man in the neighborhood quite frequently, but did not know his name or where he kept. He, however, described him to Seide as a tall, well-built man, with dark moustache and dark complexion. The reporter started out, and visited the truck stands between Christopher and Twentieth streets, but could not find his man. Returning to Scherrer’s, he found a man, whom he describes as a “dilapidated individual,” taking a drink at the bar. Seide again asked Scherrer for a description of the truckman. Scherrer gave it as before, adding that he drove a red truck with one brown horse. Here the “dilapidated individual” spoke up and said, the truckman might be found at Christopher and Bleecker streets. On inquiring there Seide learned that he changed his stand a few days before; but where he had gone no one in the immediate vicinity could tell. He, however, discovered that his name was C. A. Strang. He then made inquiries for Strang’s whereabouts in various smithies and liquor stores, and in one of the latter he ascertained that Strang lived in Greenwich street, on the west side, a few doors below Christopher street.
