I didn't get to see the actual broadcast as I don't have cable, but someone mentioned on the neworleans community that Chris' murder was mentioned on Anderson Cooper's 360 yesterday (July 16). I can't find a clip yet, but here's the excerpt of dialogue from the transcript:

(full transcript of 360 here)

RANDI KAYE, CNN CORRESPONDENT (voice-over): The floodwaters long gone, New Orleans is drowning in murder.

(on camera): Do you feel safe here in the city here now?

UNIDENTIFIED FEMALE: Not really.

KAYE: Jeannette Kelly's (ph) boyfriend, Christopher Roberts, was shot and killed just last month on Father's Day. Police say someone stole his motorcycle and Roberts took a bullets to the chest. His killer, like too many here, got away.

UNIDENTIFIED FEMALE: I think that some people have lost their humanity, have no appreciation for life. And I don't know. It's a really sad reflection on our society.

KAYE: The couple had evacuated for Katrina and moved back last December with their new baby girl. They wanted to help rebuild, just like their neighbor, filmmaker Helen Hill, who was shot to death in January by an intruder who was never caught.

After hear murder, Kelly says she and her boyfriend put bars on their windows and bought a gun. They thought that would keep them safe.

The week Helen Hill died, there were 11 other murders, prompting New Orleans Mayor Ray Nagin to make this promise.

RAY NAGIN (D), MAYOR OF NEW ORLEANS: We will put all of our resources to focus on murders and violent crime, everything we have.
