Is playing violent video games a healthy way to deal with tragedy?

Posted under Ask the Mediatrician.

Q: My nephew and niece’s mother died due to a tragic accident. She was shot by her 13-year-old son. How can I tell if they are dealing with this tragedy in a healthy way? He continues to play violent video games with graphic shooting and killing people. Is this normal behavior?
