BILL HEMMER, CNN ANCHOR: Neighbors say they were distraught when hearing of the crime. For one neighbor, it is especially difficult. Brendan Keefe from our affiliate KPRC reports.</s>BRENDAN KEEFE, CNN CORRESPONDENT (voice-over): This is 7-year- old Noah swinging at the pinata at a Saturday birthday party. He was found dead in the bathtub. John was just five years old. Raymond Rivera was holding the pinata; he finds these images hard to watch.</s>RAYMOND RIVERA, NEIGHBOR: They were out there having a good time. And then you hear -- after that, they come to the party. And they look like they're having a good time and everything, and the next thing you know, they are not here anymore.</s>KEEFE: Not here anymore. Paul, aged 3. What makes this video to difficult to watch is knowing that these three children and their brother and sister are now dead. (on camera): Those pictures were taken just five days ago. The entire family invited over for cookout. Only the dad and three of the oldest boys came over. It was the last time the neighbors saw those boys alive. (voice-over): Rivera says the mother refused to come over to the party last Saturday because she was suffering from severe depression, that police say may have led to the murders.</s>RIVERA: They seemed so nice and everything. I just figured it was the beginning of them coming over and being able to swim at my pool and stuff like that, because I invited them when ever they wanted to come back to swim and stuff like that. But now, we can't even have them over.
