(KSHB) A Missouri teen says her school bus driver was watching pornography on his phone, not realizing she’d stayed on board to wait for her friends during a field trip. 

The Raytown High senior said was caroling with the choir at different schools within the district earlier this month. At their fifth and final stop, the 17-year-old said she didn’t feel good, so she stayed on the bus.

“She was crouched down in her seat with a coat over her, she was in the middle of the bus,” the student’s mother said. “Then about five minutes, maybe a little bit less than that, she started hearing pornography sounds from the bus driver’s phone, and then she also heard him self-pleasuring himself.”

She said her daughter stayed still for half-an-hour, so the driver wouldn’t know she was on the bus. When the choir came back on board, the teen immediately reported what she heard to her choir director and filed a police report.

On Tuesday, a KCPD spokesperson told NBC affiliate KSHB that a sex crimes detective took the case to the prosecutor’s office, but because there wasn’t evidence that the teen saw the bus driver’s actions, they couldn’t file charges. 

“The school district did assure me that he would never drive again in the Raytown school district,” the mother said.
