Headline says "4" first sentence says "5 transients".
"Long Beach police said the 2008 shooting deaths of five transients at a homeless encampment was sparked by one victim's unpaid drug debt. Two gunmen allegedly killed the man, then fatally shot the others in the encampment to prevent them from being witnesses against them, police said "
The short article is not very informative. Were the alleged gunmen arrested and are now in jail? Who is the woman in photo accompanying article? What lead police to them? I would also say "what took them so long to find out who the killers were?" except, I guess it takes that long to follow up on leads, and gather enough evidence to file charges.
