We report on the detailed analysis of three candidate blue straggler stars, S277, S997, and S1031, in the old open cluster M67 (NGC 2682), based on observations made with the high resolution Immersion GRating INfrared Spectrograph (IGRINS) at the McDonald Observatory 2.7m telescope at a resolving power of R~45,000. Species analyzed include C, Mg, Al, Si, S, Ca, Fe, and Ni from atomic features in the H and K bands.
