MCPHERSON, KS. – Ten people on their way back to Oklahoma City had to be hospitalized due to a carbon monoxide leak inside a church van.

According to KWCH, the group was heading back to Oklahoma City from Kansas when it happened.

They pulled into a gas station, showing signs of carbon monoxide poisoning.
