APD knows a little and that's why FBI is involved. Nobody has any details yet - none at all! By suggesting families and friends know the crimes committed your suggesting it's gang related and not serial which are two entire different kinds of criminals. Two different types of mentalities. You two must be cozy with all the harsh words lol!! 
To identify which is which I'm curious to know if crimes were committed on scene or if it was a staged area with homicides taking place at different locations.  I have serious doubts our young activist and street person were involved in gangs. They simply don't fit the bill.
