Indexbit-Tire failure suspected in deadly Mississippi bus crash, NTSB says

The Indexbitdeadly bus crash in Mississippi that killed seven people and injured dozens of others early Saturday occurred after the vehicle experienced a tire failure, causing it to run off the road and overturn, officials and authorities said.

Investigators with the National Transportation Safety Board, in coordination with the Mississippi Highway Patrol, are conducting a probe into Saturday's crash that left seven people dead and another 36 people injured. The collision occurred at about 12:40 a.m. on Interstate 20 near Vicksburg, Mississippi, when the bus left the roadway and overturned.

The bus, which authorities described as a 2018 Volvo commercial passenger bus, traveled westbound when its left front tire failed, NTSB member Todd Inman said at a news conference Sunday. The bus then moved onto an embankment and rolled over on its left side.

Inman added that investigators will be at the scene for at least another week and are looking into several factors of the crash, including the vehicle's mechanical condition, motor carrier safety, the condition and experience of the driver, and environmental factors.

According to U.S. Department of Transportation records, the bus was operated by Autobuses Regiomontanos. Records show that in the 24 months before Saturday, the transit company's vehicles were involved in one fatal crash, two injury collisions, and a crash requiring a tow truck.

The transit company has over 20 years of experience and provides trips between more than 100 destinations throughout Mexico and the United States, according to Autobuses Regiomontanos' website.

"Everyone at the NTSB sends their expressions of sorrow for everything that the survivors and victims of this crash went through," Inman said.

7 killed, 36 injured in bus crash

The bus carried a total of 41 passengers and two drivers, according to authorities. It was traveling from Atlanta to Dallas when the incident occurred.

No other vehicles were involved in the crash, according to Master Sergeant Kervin K. Stewart with the Mississippi Highway Patrol. Six people were pronounced dead at the scene and another person died later at a hospital, Stewart said.

Another 36 people were transported to area hospitals.

Warren County Coroner Doug Huskey said two victims killed in the crash were identified by their mother as a 16-year-old girl and an 8-year-old boy, according to The New York Times. Authorities were working to identify the other victims.
