The BAU is called to San Bernardino, California where two home invasions have occurred within four days of each other, the two taking place within one block of each other. In both cases, the homes belonged to Caucasian families, in both cases the father had a gun and weapons training, and in both cases all family members were killed, all by gunshot. At each scene was also one deceased member from among the intruders, both black males. While one of those black deceased was known to be involved in gang activity, the other was seemingly a hard working model citizen, who was working two jobs to put himself through school. As well, both deceased black males had massive doses of oxycodone in their system. These murders are being used as political fodder within the current San Bernardino mayoral race, with Caucasian candidate Clark Preston using inflammatory wording to describe the ensuing race wars from these home invasions between the whites and "the browns". The BAU have to figure out if Preston is somehow directly involved or if his rhetoric is stirring up these sentiments of someone unrelated to him.
