(ELIZABETHTOWN, Ky.) — One person has died and two others were injured after a Denny’s sign fell and crushed a car in Elizabethtown, Kentucky, officials said.

The sign fell and crushed an occupied car at the chain restaurant on Thursday, Elizabethtown public affairs officer Chris Denham told ABC News.

Officials received a call at around 1:30 p.m. about the incident, and the Hardin County EMS and fire department responded to the scene, he said.

Two victims were taken to Baptist Health Hardin hospital, and a 72-year-old woman with more severe injuries was taken to the University of Louisville, where she later succumbed to her injuries, Denham said.

The other victims are being treated at Baptist Health Hardin.

It’s unknown what caused the sign to fall.

The investigation is ongoing and in its early stages, Denham said.

ABC News has reached out to Denny’s.

(EVANSVILLE, Ind.) — At least one person was shot and wounded at a Walmart in southern Indiana on Thursday night when a former employee opened fire inside the store, police said.

The gunman was ultimately killed in a minuteslong shootout with police.

The incident unfolded just before 10 p.m. local time at the Walmart in the West Side neighborhood of Evansville, a riverside city about 180 miles southwest of Indianapolis. The suspect — identified as 25-year-old Ronald Ray Mosley II — allegedly walked into the store and began shooting, according to the Evansville Police Department.

Officers were quickly deployed to the scene and immediately entered the Walmart looking for the gunman, as people tried to hide or flee. It was unknown how many people were inside the store at the time and how many of them were shot at, police said.

Seven Evansville Police officers and one Vanderburgh County Sheriff’s deputy exchanged gunfire with the suspect both inside and outside the store, in multiple different areas, though the exact number of rounds was unclear, according to police.

“Multiple times he was actually shooting at officers before they were actually able to shoot him,” Sgt. Anna Gray of the Evansville Police Department said at a press conference late Thursday. “At this time, we don’t believe there are any other suspects involved in this.”

The suspect was pronounced dead inside the store. The entire incident lasted about 15 minutes and no officers were injured, according to police.

A woman with a gunshot wound was transported from the scene to a local hospital. Her condition was unknown, police said.

“A lot of people were running out, so there could be more [victims] out there,” Gray told reporters. “If someone was directly involved or injured during the incident, please either come back to the scene or call 911 and give us that information. We are looking for any other victims at this time.”

The suspect had a criminal history and used to work at Walmart. He and the wounded victim may have been coworkers at one time, according to police.

“This is a tragic incident. We can’t imagine what the witnesses and employees and customers inside went through,” Officer Taylor Merriss of the Evansville Police Department said at a press conference early Friday. “But without the bravery and professionalism of our department, there could’ve been a lot more lives lost last night.”

The shooting remains under investigation. In addition to collecting evidence from the scene and interviewing witnesses, investigators are reviewing footage from the responding officers’ body-worn cameras as well as from the Walmart’s security cameras, according to police.

Walmart told ABC News in a statement late Thursday that it “is shocked by the senseless violence that occurred at our Evansville store.”

“As we learn more, we’ll do everything we can to support our associates as they cope with this tragedy,” the company added. “We’re thankful for the local first responders and will continue working with law enforcement through the course of their investigation.”

(WASHINGTON) — The Federal Aviation Administration said Thursday that last week’s computer system outage, which caused thousands of flight delays across the United States and a temporary grounding of the nation’s airspace, appears to have been the result of “unintentionally deleted files.”

“A preliminary FAA review of last week’s outage of the Notice to Air Missions (NOTAM) system determined that contract personnel unintentionally deleted files while working to correct synchronization between the live primary database and a backup database,” the FAA said in a statement. “The agency has so far found no evidence of a cyber-attack or malicious intent. The FAA continues to investigate the circumstances surrounding the outage.”

“The FAA made the necessary repairs to the system and has taken steps to make the NOTAM system more resilient,” the FAA added. “The agency is acting quickly to adopt any other lessons learned in our efforts to ensure the continuing robustness of the nation’s air traffic control system.”

The FAA’s NOTAM system is critical to flight operations — it keeps pilots informed of essential information that’s needed before takeoff, such as runway conditions at destination airports, weather en route and even real-time safety alerts during flight. Notably, the system is overdue for replacement.

When the FAA first reported an issue with the NOTAM system late in the night on Jan. 10, it led to a “cascading” series of IT failures culminating in the nationwide disruption the next morning, a senior official briefed on the matter official told ABC News. By mid-day, there were more than 7,300 flight delays and 1,100 cancellations, according to tracking website Flight Aware.

The official compared the NOTAM system outage to the crisis that crippled Southwest Airlines over the winter holidays: antiquated software overdue for replacement inside a critical IT network. If one thing goes down, the system can become paralyzed.

The issue apparently occurred during routine scheduled systems maintenance, a senior official briefed on the internal review told ABC News. An engineer “replaced one file with another,” the official said, not realizing the mistake was being made. As the NOTAM system began showing problems and ultimately failed, FAA staff feverishly tried to figure out what had gone wrong. Engineers and IT teams are now working to keep the system from crashing again, while also trying to figure out if there are any similar systems that could fail without redundancies.

Congressional hearings on the matter are expected in the coming weeks, as is a possible speed-up of system replacement.

Several airlines, including American, Delta and United, are waiving fees to rebook flights due to last week’s disruption.

(ATLANTA) — A woman has been arrested after assaulting flight attendants and police officers when she discharged and sprayed a fire extinguisher at them during a confrontation at one of the nation’s busiest airports.

The incident occurred at approximately 9:34 p.m. on Wednesday night when the Atlanta Police Department responded to a call on concourse D at Atlanta’s Hartsfield-Jackson International Airport regarding a “suspicious female attempting to open secured doors inside the concourse,” the Atlanta Police Department said in a statement.

“Officers were advised a female, identified as Jennifer Holder, was in gate D-9 discharging a fire extinguisher inside the concourse,” authorities said. “Officers attempted to make contact with the female, but she was non-compliant and sprayed officers with the fire extinguisher.”

Officers were able to detain Holder shortly after, in spite of being assaulted, and three airport flight attendants with complaints of respiratory discomfort were treated at the scene, according to the Atlanta Police Department.

Holder reportedly continued to resist arrest after being detained and behaved “erratically and combative by spitting and kicking at officers,” authorities said.

Authorities have not yet given a reason or potential motivation to the incident as the investigation is ongoing.

The suspect was evaluated by EMS personnel for minor injuries she self-sustained during the incident before being taken to the Clayton County Jail.

Holder now has several charges pending against her, including assault, and the investigation into the incident continues.
