SPRINGFIELD — Late-afternoon gamblers strolling past the baccarat table ignored its sole player, a brooding dark-haired man whose gaze rarely left the table. He wore a white N95 mask, purple nitrile gloves and a lightweight hoodie the color of his chips, a bluish gray.
On her rounds at MGM Springfield, Amy Gabrila noticed him right away. The golden RESERVED placard on the table marked him as a high roller, as did the color and quantity of his chips. Grays are the color of money in Massachusetts casinos, each worth $5,000.
