On the day of the attack, Sunday, July 17, officials announced that they shot and killed the suspect, who was later identified as Gavin Long, a 29-year-old man from Missouri. Long's body was released to his family on Monday, July 25.    

The day of the attack, officials did fear two additional suspects were involved. Investigators detained and questioned two suspicious people who were located in the neighboring West Baton Rouge Parish after members of the public called 911 about two suspicious men who were seen entering the Walmart in Port Allen.

They say the men were dressed in all black, they changed clothes inside the store, then left in a silver Nissan with a Texas license plate. The men were released Sunday evening after being questioned by the FBI. Investigators said they had no connection to the shooting. 

In the hours following the shooting, officials say there were reports of gunfire in several areas around the city, but so far those reports have all been unfounded. Law enforcement agencies throughout Baton Rouge remain on high alert.

On Monday, July 18, top officials were joined by Louisiana Gov. John Bel Edwards for a news conference to announce details of the investigation. They revealed that fingerprint analysis positively confirmed Long as the gunman and added they believe he acted alone. Col. Mike Edmonson, superintendent of Louisiana State Police, confirmed the timeline of events and used large pictures of the crime scene to walk reporters through the shooting. The images were obtained from surveillance footage.  

The initial caller at roughly 8:40 a.m. reported a man holding a rifle, wearing all black, who was standing behind a beauty supply store on Airline Highway. The scene later shifted to the nearby B-Quik gas station, which is located less than a mile from BRPD Headquarters.

During a call to dispatch, an officer said, "unknown where the shots are coming from." Dispatch audio.

A witness described hearing at least 25 to 30 gunshots when the shooting began. 

According to Edmonson, Long first shot and killed two police officers and a sheriff's deputy near the Beauty Supply store next to the B-Quik convenience store. Edmonson said Long then sprinted along the back of the buildings to the Fitness Expo where his car was parked. Edmonson added Long then started firing at a BRPD SWAT Team officer, who fired back with the fatal shot hitting Long from over 100 yards away.

Investigators recovered three guns that were analyzed to determine ownership. They include an IWI Tavor SAR, 5.56 caliber rifle, Springfield XD 9, 9mm caliber pistol, and Stag Arms M4 Variant, 5.56 caliber rifle was staged at the vehicle. The vehicle is a Chevy Malibu that was rented from Missouri. It was recovered at the scene. 

The East Baton Rouge Parish coroner released autopsy results Wednesday, July 20 that confirm Long died from multiple gunshot wounds. 

On the same day the VA confirmed that Long was a veteran who served in the Marines. They also confirmed that he sought medical attention over the course of several years after he was deployed overseas. 

Dr. Boyce Watkins of the Black Business School received an email from Long on Monday, July 11 at 10:31 p.m., just one day before the Louisiana State Police says Long rented the car he drove from Kansas City, Missouri to Baton Rouge. In the letter he spoke specifically about the Alton Sterling investigation. 

Alton Sterling died Tuesday, July 5 after he was shot by a Baton Rouge police officer outside the Triple S Food Mart. Police were initially called to the store from a complaint that a man with a gun was outside the store selling CDs and had threatened someone.

Protests were held throughout Baton Rouge the weekend following his death and continued on a smaller scale the following week. 

Sterling's funeral was held Friday, July 15 at Southern University.
