They are having a news conference now so I'm sure we will hear more soon. From reading all the other news stations and newspapers here  it sounds like they all started squealing on each other.  Three have a criminal record and the victim was an acquaintance of someone in the area where this attack happened. 

I'll post an update when information is put together and not scattered across a bunch of news sites.
