"It is a horrific scene and to be able to process it will take some time,” Officer Mike Swafford of the sheriff's office told a local TV news station. “We don’t have a motive at this time. We don’t have a determined suspect at this time. Investigators are following leads to piece together exactly what happened and who was involved. We can say we don’t believe there is an active threat to anybody in the area.”.
