HARRIS COUNTY, Texas — The toxicology report is in for the school bus driver who was accused of driving while intoxicated with 20 students on her bus. 

According to the report, Linda Sue Godejohn had four controlled substances in her system, aminoclonazepam, clonazepam, meprobamate and carisoprodol. The drugs are a muscle relaxer, anti-anxiety medication and sedative.

According to the National Institutes of Health, you shouldn't drive on any of the medications until you know how they affect you. 

Godejohn was taken into custody on May 30 near Aldine Westfield and Hirschfield Road after several people spotted her driving erratically and called 911.

One parent followed the bus, ordered Godejohn to stop and waited on deputies to get to the scene.

Deputies said Godejohn showed signs of intoxication but she claimed she was just sick from eating a donut. 

Precinct 4 Constable Mark Herman said that excuse won't hold up in court because Godejohn was driving erratically before she stopped to get the donut.

"In reviewing the video — from almost the moment she left to get her bus, she was all over the roadway," Precinct 4 Constable Mark Herman said. 

He said Godejohn failed the field sobriety test miserably.

"Initially they thought that maybe she was impaired by alcohol — but just to cover our bases we went ahead and did a blood draw," Herman said.

Godejohn was originally charged with driving while intoxicated, but her charges were upgraded to driving while intoxicated with a child under 15 years of age.

Godejohn is out of jail on bond. Her next court date is scheduled for Aug 6.

She was contracted by YES Prep Public Schools who expressed their frustrations if the allegations are true.
