There’s one other curious thing. By FBI standards....it’s a mass murder (four or more dead), yet all by knife. It’ll be considered one of the statistical odd things about 2015.

Knife or fire. They could have been burned alive. From the article:

Sources close to the investigation told WTTG that Savvas and Amy Savopouloses, as well as Figueroa, were all found dead in chairs and were doused with gasoline. Philip Savopoulos was found in his bed, burned beyond recognition and with lacerations to his body.

I’m sure a gun was involved to keep the victims compliant. The gun would have made too much noise, going off 4 times.
The animals used the knives to keep things quiet.

The terrible and truly sad definition of SHEEP.
