Law & Order Season 16 Episode 14 Magnet

Detectives Fontana and Green investigate the strangling of a promising Hispanic student at a private magnet school. The men soon learn the victim was selling test answers and writing term papers for more privileged students -- including their prime suspect, Greg Loomis, a trouble-prone senior who would kill just to graduate.

After Loomis' arrest, A.D.A. Sam McCoy spurns any deal with his high-powered attorney Rebecca Shane but has to overcome her vigorous defense that her client himself was a victim of medication side effects.
