Days after police shot them, the investigations into the deaths of Philando Castile and Alton Sterling are far from over.
But new details are emerging in the two cases that have sparked protests nationwide and debate over whether officers used excessive force.
Here's a look at the latest developments:
Police chief: Governor's claim 'hurt me'
What happened after the video that showed Castile bleeding inside a car went black?
Rick Mathwig says recent reports don't line up with reality. Mathwig is the police chief in Roseville, Minnesota. His officers weren't the ones who pulled over Castile or fired the fatal gunshots. But they responded to the scene in Falcon Heights after the shooting. And in an interview with CNN, Mathwig made several points:
• Officers started administering CPR three minutes after arriving at the scene, trying to save Castile's life, Mathwig says. "It hurt me … to hear the governor of Minnesota saying that Mr. Castile did not receive CPR," he says.
• Diamond Reynolds, Castile's fiancée who recorded the shooting aftermath in a Facebook Live video, wasn't detained by police all night, Mathwig says. The police chief says she was held for about two hours in what's called a "soft interview room" because it also contains toys, books and blankets.
• Mathwig says investigators did what they could to help Reynolds and her 4-year-old daughter. Before dropping her off at home, Mathwig says an officer gave the child a teddy bear.
Judge Glenda Hatchett, an attorney for the Castile family, told CNN on Wednesday that the investigation into what happened leading up to the shooting — and afterward — is just beginning.
"Was there a delay? There's a question about whether he was taken to the closest trauma center," she said. "There are a lot of unanswered questions."
Racial profiling?
As the investigation continues, details are emerging about Castile's past encounters with police. Since 2002, law enforcement in Minnesota had pulled over the school cafeteria supervisor at least 52 times for misdemeanors such as driving without proof of insurance, according to state court records. Many of the cases against him were dismissed.
Castile was pulled over an average of more than three times a year — something that protesters argue is a sign of racial profiling.
One profiling expert told CNN he agreed.
"I would say that, looking at the record, it's consistent with a pattern of being racially profiled," says Myron Orfield, a professor of civil rights and civil liberties law at the University of Minnesota.
"He's got an awful lot of stops," Orfield says. "It suggests a pattern of very excessive policing."
An attorney for the officer who shot Castile says the shooting had nothing to do with race and everything to do with a gun being present at the scene.
Sterling's son: Protests should be peaceful
Sterling's 15-year-old son, Cameron, is calling for calm.
"Everyone needs to protest in the right way — with peace, not violence," he said Wednesday. "No violence whatsoever."
Standing outside the Baton Rouge, Louisiana, convenience store where his father was shot dead, the teen said the shooting should unite people, not divide them.
"Everyone needs to be on one chord, not a different note. Everyone needs to be together, not apart," he said. "And I truly feel that my father was a good man, and he will always be a good man."
Baton Rouge officer: Sterling reached for gun
A Baton Rouge detective says the police officers who fatally shot Sterling did so after seeing him reach for a gun.
In a search warrant affidavit seeking surveillance video from the store, Detective R. Cook wrote that the Baton Rouge officers deployed their Tasers after Sterling did not comply with their orders.
"While the officers were attempting to subdue the subject, the officers observed the butt of a gun in the subject's front pants pocket," Cook wrote.
"When the subject attempted to reach for the gun from his pockets the officers fired their police issued duty weapon at the subject to stop the threat. The subject was shot multiple times and did not survive his injuries."
