Factual and procedural background
Kim Rushton was a 68-year-old man who worked as a chemist in a water lab for the City of Los Angeles to test water samples for organic molecules. Rushton had been employed in his job for more than 20 years. He received medical treatment for several medical conditions, including occasional seizures, neuropathy in his feet, and tremors that were controlled with medications. In Dec. 2014, Rushton fell at his job and remained off from work until Feb. 2015 because of his fall-related injuries. He was allowed to return to work on Feb. 2, 2015, with restrictions on kneeling, squatting, and bending. He was also restricted from sitting or standing for longer than four hours. The doctor did not place any restrictions on his ability to drive, however. On Feb. 20, 2015, Rushton was given an injection of steroids to ease his back pain.
