Mass Murders In Europe Again

From the April 9, 2013 Canadian National Post:

VELIKA IVANCA, Serbia — A 60-year-old veteran gunned down 13 people in Serbia, including his mother, his son and a two-year-old cousin, in a pre-dawn house-to-house rampage Tuesday before shooting himself and his wife, police and hospital officials said.

The man, identified as Ljubisa Bogdanovic, used a handgun in the shooting spree at five houses in Velika Ivanca, a village 50 kilometres southeast of Belgrade, emergency hospital spokeswoman Nada Macura said.

Twelve people were killed immediately between 5 a.m. and 5:30 a.m. and one person died in a Belgrade hospital, Serbian police chief Milorad Veljovic said. The man and his wife were both severely injured by the shootings and another person was also injured, Macura said.

Ordinarily, there is a history of mental illness in these cases.  This is a bit more complicated:

Macura, the hospital spokeswoman, said the shooter had no known history of mental illness. Stanica Kostadinovic, another neighbor, said the man’s father had hanged himself when he was a young boy and his uncle had a history of mental illness.

Because mental illness runs in families, I find myself wondering if it was not recognized, or developed suddenly.
