A new study is out regarding mass killings. The government doesn't report a lot of shootings; only some of them actually get mentioned to the public. At least 172 mass killings happened between 2006 and 2011. Public massacres are 1 in 6 of the mass killings.  Around 50% of the killings are family. Relationship problems, and the holidays are two other causes of killings. 6 year olds are the second most killed age group. Around 94% of mass killings are done by men, while women only account for 4%.
