A district official said the system failed to detect the shooter's handgun because of where cameras were in the school.

Police said the suspect fatally shot himself after killing a 16-year-old and wounding a 17-year-old at Antioch High School.

The shooter was “significantly influenced by web-based material, especially that found on non-traditional sites that most would find harmful and objectionable,” police said.

Police said the suspected shooter sustained a self-inflicted gunshot wound and the school district said Antioch High School is on lockdown.
