Another mass shooting in Brazil: Despite extremely strict gun control laws and only a few percent of the population owning guns

A total of seven people were killed in this mass shooting.  From the Voice of Russia:

The motive of the crime late Thursday in Realengo was unknown, police spokesman Pablo Rodrigues said. 

"We cannot rule out any hypotheses," he said. "We will investigate the chance that the massacre might have been caused by the group's debts with drug dealers. That is one hypothesis, but we have not ruled out others."  

Five men and two women, aged 21 to 37, were killed by handguns and rifles on the veranda of the house, local media reported. . . .
