Chilling Doorbell Footage Captures Austin Shooter’s Final Moments Before Tragic Massacre

Newly surfaced footage from a doorbell camera reveals the suspect involved in the Austin mass shooting visiting an apartment just before the tragic event.

In this video, acquired by FOX 7, 53-year-old Ndiaga Diagne is spotted departing from an apartment in Del Valle, Texas, as captured by a nearby doorbell camera.

The timestamp on the video is marked February 28, merely a day prior to the mass shooting incident.

The same neighbor also shared footage showing FBI agents obscuring the camera just moments before conducting a raid on Diagne’s apartment on March 2. This operation was part of executing a search warrant at an apartment associated with Diagne.

On the previous day, residents at Eastridge Apartments experienced an intense scene when federal agents surrounded a unit in the complex around 11:30 a.m. One agent used a loudspeaker to instruct anyone in unit 813 to move away from the windows, as reported by the outlet.

Shortly after, neighbors heard a noise that they described as sounding like gunfire. 

“Then we heard like, gunshots, and then we heard a grenade, like a grenade bomb go off in the apartment. It was just a lot of cars and the FBI with their guns drawn,” one anonymous resident told FOX 7. 

Another resident detailed how they encountered armed agents outside their apartment upon returning home. 

“I looked through the window from the restroom, and I just saw them right in the house, and they had a car in the grass right there. They had K-9s waiting too, they had rifles outside the gate,” Alex Sky said.

After entering the apartment, federal agents remained inside for several hours – marking the second location law enforcement has searched in connection with Diagne. 

A second home in Pflugerville was also searched on Sunday, with ATF agents carrying boxes believed to contain evidence outside. 

It remains unclear if anyone was inside the apartment at the time the search warrant was executed. 

The footage comes after four people, including the gunman, were killed in a mass shooting at Buford’s Backyard Beer Garden in Austin just after 2 a.m. Sunday.

Savitha Shan, 21, Jorge Pederson, 30, and Ryder Harrington, 19, have all been identified as victims in the incident, according to the Austin Police Department. 

According to Police Chief Lisa Davis, the gunman – who was a 53-year-old naturalized U.S. citizen born in Senegal who lived in Pflugerville – “put his flashers on, rolled down his window and began using a pistol shooting out of his car windows, striking patrons of the bar that were on the patio and that were in front of the bar.” 

Following the initial shooting, the gunman then drove westbound on Sixth Street to Wood Street, parked his vehicle and exited holding a rifle while continuing to shoot at pedestrians without ever entering the bar.

He was then shot and killed by police at the scene.

The FBI has since classified the shooting as a possible act of terrorism.

“Obviously, it’s still way too early in the process to determine an exact motivation, but there were indicators on the subject and in his vehicle that indicate potential nexus to terrorism,” Alex Doran, acting special agent in charge of the FBI’s San Antonio Field Office, said at a press conference Sunday.

“Again, it’s still too early to make a determination on that. That’s why we are investigating it very closely with our partners with the Austin Police Department,” Doran added.

Additionally, the FBI’s Joint Terrorism Task Force has also been deployed. 

“We’re just at this point prepared to say that it was potentially an act of terrorism,” he said.

At least two additional victims remain in critical condition, according to authorities.
