At the factory, Gillette met Grace Brown, another employee. Gillette and Brown soon began a
sexual relationship, with Brown assuming Gillette would
marry her. In the spring of 1906, Brown revealed that she was pregnant. She continued to pressure Gillette to marry her, often writing him pleading letters. Brown then returned to her parents' home for a time, but returned to Cortland when she discovered that Gillette had been courting other girls. One popular story involved Miss Harriet Benedict, a wealthy acquaintance of Gillette who the newspapers later speculated was the "other woman" for whom Chester had left Grace. Harriet heatedly denied this, going so far as to issue a formal
press release proclaiming: "I have never been engaged to Chester E. Gillette ... Our acquaintance was of ... a limited duration, and ... not a word or suggestion was ever made between us [about an engagement]." As the spring and summer of 1906 progressed, others noticed an increasing frequency of Gillette's raised voice and Brown's tears at the factory or at each other's homes. Brown continued to press Gillette for some kind of decision, and Gillette played for time with vague statements about their future and of their going away on a trip sometime soon. Finally, Gillette made arrangements for a trip to the
Adirondack Mountains in upstate New York. The pair stayed for a night in
Utica, New York, and then continued to
Tupper Lake in
Franklin County, spending the night. Rain the next day ruined their plans for an outing on a nearby lake, so they returned south to
Big Moose Lake in
Herkimer County. At the lakeside Glenmore Hotel, Gillette registered under a false name (although one that used his own initials to match the monogram on his suitcase). He was carrying one suitcase and a tennis racquet. Brown, at this point, may have expected some kind of elopement ceremony. On July 11, Gillette took Brown in a
rowboat on Big Moose Lake, where he clubbed her with his tennis racquet and left her to drown. An overturned boat was found floating in the lake, together with Gillette's hat, leading authorities initially to believe both had drowned. Meanwhile, Gillette, carrying a suitcase, hiked through the woods to
Fulton Chain Lakes, where he checked into the Arrowhead Hotel under his real name. Later, witnesses said that Gillette seemed calm, collected, and perfectly at ease; nothing seemed to be amiss. Brown's body was found at the bottom of the lake the next day. An autopsy revealed she had suffered major head trauma, turning an accidental drowning case into a murder investigation. Gillette had done a poor job of planning the cover-up, and was quickly arrested in nearby
Inlet, New York. Grace Brown was buried in Valley View Cemetery in her hometown,
South Otselic, New York. == Trial and execution ==
