CHICAGO: A gunman opened fire in a crowded US movie theater and shot two people dead before killing himself Thursday, shortly after President Barack Obama expressed frustration with weak gun controls. More than 100 people were in the theater when the gunman began shooting randomly with a handgun about 30 minutes into a showing of “Trainwreck” at the Grand 16 theater in Lafayette, Louisiana, police said. Nine people were injured, some critically. President Barack Obama said earlier Thursday that a “distressing” lack of progress on gun control legislation had been the greatest source of frustration during his time in office. This latest mass US shooting comes as a jury deliberates the death penalty for the gunman in a 2012 theater massacre in Colorado that left 12 dead and 70 injured.
