Edgar Naranjo was freed after serving half of a 40-year sentence. Critics say his case shows what’s wrong with the felony murder law.

In 2002, Edgar Naranjo was a 26-year-old drug addict desperate for money. He hatched a plan to rob a flea market vendor he figured had a large supply of cologne he could unload for cash. His haphazard scheme went badly awry. After Naranjo and a teenage accomplice broke into their target’s Northwest Side home, the vendor’s son, a Chicago police officer, shot and killed the younger intruder and wounded Naranjo, who was later arrested after seeking treatment.
