On Tuesday, Freeport police said a driver lost control and flipped on Highway 36.
The cause of the crash is under investigation. On Wednesday, the chief told Eyewitness News the district attorney's office plans to hire an agency to exam the bus, and evidence from the crash.

The bus was carrying Zachry Construction workers from the plant to a lot where their vehicles were parked.
Thirty employees were injured. Aaron Green was killed. He leaves behind two children and a wife.
"He was our everything," Green's wife, Shawna Green said. "Our everything, and I will do everything I can to make him proud."
Green's family spoke exclusively to Eyewitness News Wednesday.
While they know he was killed in the crash, they're still waiting to find out more information.
"We don't have answers," Green said. "We don't know what's going on. We don't know what happened."
Family members said Green worked as a pipe fitter at Zachry Construction.
"He jumped in it all the way and learned, and within two years, was considered a top hand," Aaron's brother, Scott Green Jr., said.
While he loved his family and job, his family said Green's passion was the Houston Astros.
"Anytime they were on," Shawna said. "Anytime they were playing. If he couldn't see it on TV, it was on his phone. It was on the radio in the car. He was a religious fan."
An intense fan that Shawna said made the house shake when the Astros won the World Series, and nearly ruined furniture as the team got bounced from the postseason this year.
"I thought he broke our recliner," she recalled.
The reality of this week is hard, but for the Green family, it might be more difficult in April when the Astros return to the field.
"I know that he'll be watching, and still wearing that Astros hat," Scott said.
