Learning that the investigation was to be held that morning, immediately upon his arrival at Bridgeport he entered the telegraph office, and sent the following dispatch: "_Arrest the servant._" It was this message which was received by the coroner, while Bucholz, all unconscious of the danger which threatened him, was relating the circumstances that had occurred the night before.
Mr.Craw communicated to no one the contents of the message he had received, and the investigation was continued as though nothing had occurred to disturb the regularity of the proceedings thus begun.
Mr.Olmstead, however, determined to allow nothing to interfere with the proper carrying out of the theory which his mind had formed, and taking the next train, he returned to South Norwalk, arriving there before Bucholz had finished his statement.
When he entered the room he found that Bucholz had not been arrested as yet, and so, instead of having this done, he resolved to place an officer in charge of him, thus preventing any attempt to escape, should such be made, and depriving him practically of the services of legal counsel.
Mr.Olmstead conducted the proceedings before the coroner, and his questioning of the various witnesses soon developed the theory he had formed, and those who were present listened with surprise as the assumption of Bucholz's guilty participation in the murder of his master was gradually unfolded.
Yet under the searching examination that followed, Bucholz never flinched; he seemed oblivious of the fact that he was suspected, and told his story in an emotionless manner, and with an innocent expression of countenance that was convincing to most of those who listened to his recital.
No person ever appeared more innocent under such trying circumstances than did this man, and but for a slight flush that now and then appeared upon his face, one would have been at a loss to discover any evidence of feeling upon his part, which would show that he was alive to the position which he then occupied.
His bearing at the investigation made him many friends who were very outspoken in their defense of Bucholz, and their belief in his entire innocence.

Mr.Olmstead, however, was resolute, and Bucholz returned to the house upon the conclusion of the testimony for that day, in charge of an officer of the law, who was instructed to treat him kindly, but under no circumstances to allow him out of his sight, and the further investigation was deferred until the following week..
