ALISO VIEJO, Calif. (AP) — Friends and colleagues of Dr. John Cheng say they were not surprised the quiet, kind and calm sports medicine physician saved others by rushing at the gunman firing on a Southern California church luncheon.
The 52-year-old father of two was known for doing all he could to protect people.
He even had taken courses to prepare for such a horrific event, concerned about the growing number of mass shootings.
Active shooter experts say that preparedness combined with Cheng's serene disposition likely gave him a proclivity for acting heroically.
Cheng was killed and five were wounded in Sunday's shooting.
Authorities credit him for saving perhaps dozens of lives.
