Video game maker Electronic Arts canceled three tournaments of its Madden NFL 19 football game to review safety protocols after a competitor who lost a tournament attacked with a gun, killing two gamers and wounding 11 others.

Police searched on Monday for a motive in the third mass shooting in Florida in two years, which left two people dead and 11 wounded in Jacksonville, before the gunman killed himself at a video game tournament.

An 11-year-old girl has taken the stand in her father's murder trial to say that she fatally shot her 9-year-old brother while acting out a video game in their dad's home.
