BALDWIN: A Mother's Day event meant to unite the community ended with people scattering just to get away from gunfire. Nineteen people were hit, including a 10-year-old boy and girl, at this Mother's Day parade in New Orleans. Amateur video shows the moment of gunfire Sunday afternoon.</s>UNIDENTIFIED MALE: Bang.</s>UNIDENTIFIED MALE: (Inaudible).</s>BALDWIN: Police have released surveillance video of a suspected shooter here. Four victims are still in the hospital. Most of the wounds they say were minor, including those of journalist Mark Hertsgaard who talked to me last hour, said he could tell the shooter was right behind him, but he didn't see a face.</s>MARK HERTSGAARD, NEW ORLEANS PARADE SHOOTING VICTIM: And the shooter was right behind me. I did not see the shooter, but I could tell from the sounds -- and I know what gunfire sounds like from previous reporting -- that the shooter was probably 10 feet behind me. You can see me there on the video I think you just showed. I heard the pop, pop, pop, pop, and saw everyone running and, like everyone else, I ran and threw myself down to the pavement. And I was lucky. I just got shot in the leg. There were a number of people who were much more seriously injured. Three people were taken to the trauma unit.</s>BALDWIN: New Orleans police are offering a $10,000 reward for information. And, again, just a reminder, we are awaiting a news conference from New Orleans police on more information into the Mother's Day shooting. Next, a chilling CNN's exclusive, Ariel Castro's two brothers sit down with CNN and reveal their thoughts on Castro's alleged house of horrors. How could they not have known? I tell you. I was in Cleveland last week. That is the question on everyone's mind. Their answer and this entire interview, next.
