Staff Photo by Dan Henry / The Chattanooga Times Free Press- 12/1/16. Attorney Dorothy Capers listens as David A. Duke, President and CEO of Durham School Services, speaks about his company, and the fatal bus crash that happened last Monday during an editorial board meeting at the Chattanooga Times Free Press on Thursday, Dec. 1, 2016.

Before the fatal Nov. 21 bus crash, Hamilton County Schools did not share all the complaints filed against the driver with Durham School Services, the company said Thursday.

In an interview with the Times Free Press, Durham CEO David Duke said the company received two complaints against 24-year-old Johnthony Walker over speeding before the crash, but the company had not seen several of the complaints received and released to the media last week by Hamilton County Schools.

Durham is contracted to provide the district's busing services, and Thursday Duke announced the company is spending several million dollars on enhanced safety measures, which include installing smart cameras on all buses and a system to better track complaints against drivers.
