[Harlow:] Well, this morning, the family of Philando Castile is still demanding answers a week after his death. An investigation is unveiling really a string of contradictions. He said, she said, including whether or not Castile received medical aid after he was shot. Our Rosa Flores is live in Minnesota with more. Look, this is this is critically important when you look at when emergency services are usually called and when you look at what the governor said the next day versus what we're now hearing from police. What are police telling you, and how does that counter what the governor said?
[Rosa Flores, Cnn Corresppondent:] Well, Poppy, all of those details are very, very important. That traffic stop happened on this street, that fatal shooting near this memorial. Like you mentioned, all new this morning, we're learning from a neighboring police department what they say they did to try to save Philando Castile's life.
[Flores:] You've seen the dramatic cell phone video of Philando Castile in a white t-shirt covered in blood after being shot by a police officer.
[Police Officer:] I told him not to reach for it! I told him to get his hand off it!
[Flores:] Now, we're hearing from police what they say happened after the camera hit the ground.
[Rick Mathwig, Roseville Chief Of Police:] We are people.
[Flores:] Roseville Police Chief Rick Mathwig says it's his officers who arrived first on scene.
[Mathwig:] At that time, our officers didn't know who had shot whom. It was a chaotic affair.
[Flores:] But within three minutes, he says, they administered CPR on the street right outside Castile's car.
[Mathwig:] One officer from Roseville of the four that did CPR showed me his blood-soaked pants of Mr. Castile's blood. Another showed me his blood-soaked boots of Mr. Castile's blood. So, Roseville officers performed professional, caring CPR on Mr. Castile and tried to save his life.
[Flores:] A clear contradiction of what Minnesota Governor Dayton said Thursday about what happened.
[Gov. Mark Dayton , Minnesota:] She recounted it this morning in front of the residence that Philando was not given first aid, nobody tended to his condition as they were attending to the condition of the police officer who did the shooting.
[Mathwig:] It hurt me as the chief of Roseville Police Department to hear the governor of Minnesota saying that Mr. Castile did not receive CPR. It hurt.
[Flores:] But that's not the only contradiction Chief Mathwig points out.
[Diamond Reynolds, Victim's Girlfriend:] I didn't arrive home until about 5:00 this morning.
[Mathwig:] She wasn't held all night. She was held for just about two hours.
[Flores:] Reynolds was held in this room, the chief says, called a soft interview room because it has toys, books, and blankets for children to play.
[Reynolds:] They manipulated me to go to the station, where they agreed to feed us and give us water, and they didn't. They separated myself and my daughter.
[Flores:] A state investigator ended up helping her that night.
[Mathwig:] She had talked about how her groceries were in the car and her child hadn't eaten all day. So Chris Olson took $40 out of his own billfold and gave it to her.
[Flores:] And before dropping her off at home just before 1:00 a.m., Chief Mathwig says a police officer gave the little girl a teddy bear. Now, since that governor's press conference, he has come out publicly several times in support of law enforcement. Right after the Dallas shooting, he thanked police for their service and for saving the lives of so many around the country.
[Chris Cuomo, Cnn Anchor:] Rosa, this isn't going to be just he said, she said. This is going to matter. This is a fundamental element of any litigation that is to come in this case. We'll stay on it. Rosa Flores, thank you. Let's take a quick break. The race for the White House growing tighter. Polls out this morning, key battleground states. Remember, this election is going to come down to not just a few states but a number of counties. That's how tight it is. We have the numbers next.
