The Drug Enforcement Administration (DEA) agents who left a 23-year-old UC San Diego student locked in a holding cell for five days without food or water received only light punishments, according to the Justice Department. In a Friday letter to Sen. Chuck Grassley (R., Iowa), the Justice Department revealed that, of the six DEA agents involved in the near-fatal incident, four received letters of reprimand and two were given week-long suspensions without pay.
