Out on a limb here...could be the son/perp went over to the Islamic side and killed his Christian relatives?
Corn rows usually but not always associated with blacks...in Santa Monica even young blond girls sometimes adapt the look. Rather cute on them, actually.
Oh sure, could be a convert, or even a muzzie family. Given official reluctance to name names, it’s getting more likely all the time.
But sometimes names are just names. Zahawri is Arabic, but not exclusively Muslim. Names like Samir could be rooted in Arabic or could be from India. Seems to be Lebanese Christians in the neighborhood.
