Three people are dead and several others injured after an accident involving a school bus south of San Antonio.
It happened just before 7 a.m. Thursday on Highway 72, just four miles west of Three Rivers.
A van hit the back of a Three Rivers ISD school bus, killing three of the seven riding in the van.
Three Rivers ISD Superintendent Kenneth Rohrbach said all 12 of their students were OK and that only a few of them sustained minor bumps and scrapes.
However, Rohrbach said when he got the call about the accident that morning, he initially thought the worst.
"The back end of the school bus was totally crushed in," said Rohrbach. "The van was flipped on its side and there were tons of emergency vehicles at the scene. So (it) kind of makes your heart sink a little bit when your kids are on that bus."
He said the school bus was headed east on Highway 72 on its way to the school when the bus driver attempted to make a right hand turn into an RV park to pick up more students. That is when a van slammed into the back of the bus.
Rohrbach said luckily, the 12 students on the bus -- grades pre-K through high school -- were all OK and that they were all riding in the front of the bus.
"Kids tend to gravitate towards the back of the bus, but for some reason this morning, they were all near the bus driver, which saved us from having more severe injuries," said Rohrbach. "If there had been children in the back of that bus, we would be dealing with a totally different situation today."
After the accident, some of the students went back to class after talking to counselors, but some of the students' parents chose to take their kids home for the day.
Rohrbach said Highway 72 is always a worry because of all the oilfield trucks.
As far as the van in the accident, school officials said they were told that all the men in the van were oilfield workers and that the driver may have fallen asleep at the wheel.
