The names were released to ABC News by Warren County Coroner Doug L. Huskey a day after the National Transportation Safety Board announced that the preliminary investigation showed a tire failure caused the motor coach to run off the road and overturn.
Huskey identified those killed in the crash as 8-year-old Kain Gutierrez and his 16-year-old sister, Perla Gutierrez. Another 16-year-old girl who died was identified as Angelica Palomino, according to Huskey.
Also killed were Miguel Ariaga, 61; Elia Guzman, 63; and Victor Aviles Garcia, 32, and his 30-year-old brother, Moises Aviles Garcia, according to Huskey.
Huskey said that due to a language barrier, Kain Gutierrez was initially identified as 6 years old.
The crash happened early Saturday, east of Vicksburg, and left 37 other people injured, according to the highway patrol.
The 2018 Volvo commercial passenger bus, traveling from Atlanta to Dallas, was driving westbound on Interstate 20 when it drove off the road Saturday just before 1 a.m. local time, according to the highway patrol.
