Smells Like Murder

S5 E10: A large box with a body stuffed inside leads Brenda in search of suspects, and she winds up with several: a scripture-thumping stepfather, a disgruntled ex-girlfriend, a buddy who was constantly being hit up for money and a landlord who simply hated the victim's guts. Gabriel is studying for the detective exam, so Brenda uses the case as a teaching tool. Meanwhile, Brenda's niece, Charlie (recurring guest star Sosie Bacon), pulls a stunt so severe that Brenda and Fritz are ready to put her on a plane home immediately.
