I haven't followed this thread at all - so this info might be old, but I'll throw it out there in case it's not -
I heard (and keep in mind, this is third-hand info, although it comes from people that know the victim) that the victim, the owner of this hair-place, Bob, was beaten with a hammer and left for dead. There was no hostage situation - and while everyone was milling about, trying to figure out what to do, this fellow died from his wounds.
Apparently the shopkeeper in the next store down kept trying to tell everyone that there were no hostages, and nobody else was in the store - and he even attempted to get into the hair place, but was refused entry.
Not offering opinions on this - just throwing it out there.
And remember I heard it from a friend who heard it from a friend.
Sorry if this is old or inaccurate.
