The card was filed in the book devoted to such literature in the office of the Detective Association. No trace of the man was obtained, however, until in January, 1878, when another postal card from the Pennsylvania detectives stated that they had heard that the man was in Cheyenne and that $500 reward would be paid for his capture. This turned out to be a false report, but early in March Gen. Cook learned through a member of the Rocky Mountain Detective Association at Little Rock that the man had been seen there, and had only left a few days previous, on a rumor that the marshal of that place was about to arrest him, and that it was believed that he had gone to Colorado, most likely to Leadville.
The next clue bringing the game nearer home was the arrival in Denver, early in May, of a modest looking little woman, who registered at the Wentworth house, standing where now the St. James stands, as Mrs. G. M. Curtis, of Marysville, Cal. Soon afterwards Mrs. Curtis left the Wentworth and went to the Inter-Ocean, where she registered under the same name. The next day, Thursday, a man registering as G. M. Curtis put in an appearance, and claimed to be the husband of the woman. He registered from Marysville. Cal., also, and she acted as if his arrival had been anticipated. After his coming he was seen frequently in company with gamblers and sporting men. Gen. Cook, of the detective association, was then sheriff. He caught a passing glimpse of him Saturday afternoon, and at once hurried to the office to look up the description of Foulk. It answered perfectly, and having found the man, the next thing to do was to capture him. To accomplish this, the first officer retired from the field and Deputy Sheriffs Frank Smith and Arnold were detailed to work up the capture. They shadowed the man all day for two or three days and until 6 o’clock of the evening of the 26th, when, being satisfied that he was the party they were after, the two repaired to the Inter-Ocean and waited for Curtis to come in to supper. His wife happened to pass through the office, and seemed to have her suspicions aroused by seeing the two men present. She walked up to the clerk and remarked in a tone loud enough to be heard by the officers, “that she would go out and meet her husband, as he seemed to be late.”
Thinking that she was trying to mislead them, the officers followed her.
Mr. Smith then motioned to Mr. Arnold to come (meanwhile keeping an eye on Mrs. F.), and said: “Get my horse; she may be going off to get into her carriage.” Arnold did as requested, and overtook Smith several squares from the hotel. He then concluded to get back to the hotel as fast as he could, for he believed this to be a game put up on them to follow madame and allow the husband to get away. Arnold went back to the Inter-Ocean as fast as possible, it being understood that if he should find Foulk there, he should arrest him at once. Smith was to stay with the woman. Meanwhile Detective Smith closely watched Mrs. Foulk, who had entered Mr. Ballin’s store, on Larimer street.
Detective Arnold had scarcely time to go back to the hotel when Mr. Smith looked around and saw Arnold coming toward him with Foulk under arrest. He had been “nabbed” with the assistance of Officer Hudson, and the two came marching up the street with their prisoner between them—each having hold of an arm.
When Arnold entered the Inter-Ocean he saw Foulk standing in the hotel office. As soon as the officer entered, Foulk seated himself on a chair. Arnold walked up as though he intended passing Foulk, and, turning suddenly, grabbed his right arm firmly. Hudson came to his assistance, and seized the other arm, giving Foulk no chance to use his revolver.
Foulk sang out in a rage, “What do you want?”
Arnold replied: “You know something about the Bloodworth murder committed in Leadville?” [This was a ruse to throw Foulk off his guard and to get him away from the hotel quietly as possible.]
Foulk said: “I know nothing about Bloodworth.”
Mr. Arnold: “You do; and you must go with us.”
