Mr. Leichsenring notified the sheriff’s office and the police as speedily as possible, and officers flocked to the scene of the robbery by the dozen. Gen. Cook was at that time neither sheriff nor chief of police, but his detective association was as active as ever and “just aching” for a neat job in which it might distinguish itself. Consequently Gen. Cook proceeded to Leichsenring’s saloon, and, after elbowing his way through the crowd of policemen and deputy sheriffs who lined the sidewalk on the outside, found Mr. Leichsenring very much excited. He welcomed Cook with open arms and asked him to go to work in the case. He offered first a reward of $500 and then of $1,000 for the recovery of the money, and proclaimed in loud tones, as Dave went out:
“I’ll give $1,000 for the capture of the thief and the money, and if Dave Cook finds him, I authorize him to take his pay out of the bag.”
The officers scattering in all directions, policemen, deputy sheriffs and private detectives, started out to scour the town. There was incentive to work for now. A big reward was offered. Mr. Cook walked quietly back to his office and put several of his best officers to work, including Joe Arnold and Capt. C. A. Hawley. He then started out himself.
He had been on the street less than an hour when he was approached by a business man and furnished with a clue which very soon led to the arrest of the guilty party. This man told the detective a story which interested him very much. It was to the effect that a man answering the description of McDonald had applied to Lou Rothgerber, the pawnbroker, doing business then, as now, on Larimer street, between Sixteenth and Seventeenth, for a peculiar kind of expensive watch, used only by horsemen in timing races, and not having anything in his show cases meeting the demands of his customer, Rothgerber procured one at the jewelry store of Messrs. Hatch, Davidson & Co., which he sold to McDonald, together with a heavy chain, for $530, receiving his payment in gold.
Proceeding to Rothgerber’s shop Mr. Cook found a policeman standing near the entrance, who being questioned stated that he had seen McDonald enter.
“Did he have any money?”
“Yes, a pile of it.”
“Where did he get it?”
“He told me that he had just sold a mine for $10,000.”
“Which way did he go?”
