"17-year-old Trayvon Martin was shot and killed by a Neighborhood Watch captain inside his own gated Orlando, Florida community where he was living with his father, stepmother and little brother."

From the same site:

"Trayvon was shot and killed by George Zimmerman as he was walking through a gated neighborhood while visiting family in Sanford, FL, which is about 20 miles north of Orlando."

So there appears to be some confusion as to whether he was living there or just visiting. In any case he should not have been murdered for walking down the street and guest Bluesman is still an asshole because he is assuming that he was doing something illegal and deserved to be killed.
