“The joy of medicine is helping people get to better health, not the clerical activity,” said Gregory Ator, the health system’s chief medical informatics officer and surgeon.

Ator had a long criminal history — evading arrest, criminal trespassing, assault, aggravated assault, stalking, and drug and alcohol abuse — and repeated forced mental health commitments.

Ator was able to cover about 10 miles before officers shot and killed him.

Authorities said 36-year-old gunman Seth Aaron Ator called 911 before and after the shootings, but a failure in communication between agencies — they were not all operating on the same radio channel — slowed the response.
