[Malveaux:] The FBI has now joined the search for a man who was killed the Good Samaritan in New Orleans. The 44-year-old Mike Ainsworth was shot in the chest while rescuing a woman from a carjacking. His two young sons lay next to him as he was dying. David Mattingly joins us now. Tell us are there any leads about the killer, the suspect and why is the FBI is now involved?
[David Mattingly, Cnn National Correspondent:] Well, Suzanne, the police chief in New Orleans was speaking to a public gathering just last night. He was trying to reassure them saying that the investigation was going well. He's not giving up a whole lot of details about what kind of leads they have or where this investigation is taking them, but he was clearly trying to let this neighborhood know that they are doing everything they possibly can. Right now, there is a composite of the suspect that has been released. He's described as in his 20s between 5'6" and 5'8" between 140, 150 pounds. There's a $5,000 reward out for any information that might lead to his arrest. Expect to see that go up as this investigation goes on much longer. But Suzanne, as you said, the FBI is involved and it starts with this case because carjacking is a federal crime. Listen.
[David Welker, Fbi Special Agent In Charge:] Initially carjacking is a federal crime so we have reached out to NOPD and offered our assistance in the investigation. They have NOPD has taken up us on our offer. And right now, I have some agents over working hand in hand with NOPD to see if we can identify the perpetrator and hopefully further this investigation.
[Mattingly:] Got some more details talking to the FBI today. They actually had agents going door to door in the neighborhood with homicide detectives trying to gather information in this case. This is not a one-time thing for the FBI and the New Orleans Police Department. They've had such a spike in violence there recently that the FBI is routinely involved, assisting the New Orleans Police Department trying to get a handle on this wave of violence Suzanne.
[Malveaux:] David, thank you. There are big bucks at play in the race for the White House. So where do all those millions come from? Our Tom Foreman follows the money.
