According to Columbus Police Chief Ricky Boren, the man who shot three people today at Doctors Hospital is Charles Johnston, 63, of Columbus.
Johnston is a retired school teacher in the Muscogee County System, according to Boren.
Johnston's mother died at the hospital in 2004, and he had apparently held a grudge against one of the nurses ever since.
At about 2:54 p.m. today, according to Boren, Johnston was in the Doctors Hospital parking lot, armed with three weapons. Boren said he used a 9 mm handgun in the shootings.

A man pulled up in a truck, Boren said, and Johnston thought he was trying to stop him; Johnston shot the man, who is in critical condition.
Then he went up to the hospital's fifth floor and shot two people. One of them, a male nurse, was killed. Another, an administrative assistant, died after surgery.
Johnston was shot by a plain clothes policeman and is in satisfactory condition after surgery in the Medical Center. He is under guard.
