The Arizona Republic states that the bus crash occurred around 4 a.m. on Monday on Interstate 10 just east of the border of California.
The bus was affiliated with the Phantom Regiment Drum and Bugle Corps, an Illinois-based musical group, and had been carrying 13 passengers at the time of the accident. The passengers consisted of support staff for the group, and after the accident took place, the musical group decided to pull out of an event they were planned to play in Mesa.
Authorities are saying that the crash took place due to the fact that one of the front tires on the bus blew out, which then led to it veering towards and hitting the median in the road, causing it to flip on its side.
The driver that died, Donna M. Howard, 55, had been partially ejected from the vehicle and had not been wearing a seatbelt at the time of the accident. All 8 of the injured passengers were transported to hospitals for their injuries, and at this time they have all been released.
