We present evidence for globular cluster stellar debris in a dwarf galaxy system (Sagittarius: Sgr) based on an analysis of high-resolution \textit{H}-band spectra from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey. add [N/Fe], [Ti/Fe], and [Ni/Fe] abundance ratios to existing sample potential members M~54; this is first time that [N/Fe] abundances are derived large...
