Alton Sterling, 37, is dead.
The U.S. Justice Department's Civil Rights Division is leading an investigation into what happened. And the president of the NAACP's local branch is calling for the city's police chief and mayor to resign.
Tensions are running high as officials vow to be transparent about how they handle the controversial case. Here's the latest on what we know:
• The officers involved in Tuesday's shooting -- Blane Salamoni and Howie Lake II -- have been placed on administrative leave. A police incident report says Sterling was shot by one of the officers but doesn't specify which.
• The U.S. attorney's office in Baton Rouge, the FBI and state police also will be involved in the investigation, Gov. John Bel Edwards said.
• "I don't plan on resigning," police Chief Carl Dabadie Jr. said in response to calls for him to step down. "We have done a lot of good in this community. We have worked very hard in this community. Do we have an issue right now? Yes. But we are working right now to bring the truth out."
• The chief vowed authorities would conduct a transparent and independent investigation. "Like you, there is a lot that we do not understand, and at this point, like you, I am demanding answers," Dabadie said. "Like you all, my prayers are with this community, and especially with the family and loved ones of Mr. Sterling, and all the members of the Baton Rouge Police Department."
• Mayor Melvin "Kip" Holden defended his city's response to Sterling's death, noting that officials had been discussing the importance of conducting an independent investigation from the outset. "It's not like we need to be hand-held and spoon-fed when it comes to doing what's right," Holden said. The mayor described Baton Rouge as an "inclusive community" with top-ranked police, fire and emergency medical services. "We have a wound right now, but we'll be healing, and making this city and parish whole again," he said.
• Authorities urged people to be peaceful if they protest the shooting. A vigil was being held Wednesday evening outside the store where Sterling was shot.
