Sedrick Clayton, a previously-law-abiding citizen, and his girlfriend, PaShea Fischer, had an argument in the bathroom of their home. The argument continued to a bedroom, where the shooter sprayed gunfire, though the article suggests it might have been in defense. In the end, PaShea and her parents, Ricky and Tricia Fischer, were shot dead, and Sedrick left the apartment with his and PaShea's 4-year old daughter.
Sedrick eventually turned himself in. So far charges haven't been filed. The child was unharmed in the incident.
