Brazilian cartoonist Glauco Villas Boas, who went by the pen name 'Glauco'.

Glauco (Glauco Villas Boas), one of Brazil’s most recognized and loved cartoonists, was killed alongside his son Raoni in a botched robbery attempt at his home in Osasco, Sao Paulo State.

According to UOL, Glauco, 53, was resting at home with the family when their home was invaded by two armed men attempting to rob them. While trying to negotiate with one of the bandits, Glauco was shot four times at close range. His son, Raoni, 25, who had arrived home from college, was also hit. The robbers fled the scene in a stolen car without taking anything.

Both Glauco, 53, and his son were taken to Albert Sabin Hospital, but neither survived their injuries and were pronounced dead.

Glauco is one of Brazil’s most popular cartoonists. He began to publish his comic strip ”Diário da Manhã” at Ribeirão Preto in the 1970s. He was awarded at the Salón Internacional de Humor de Piracicaba in 1977 and 1978 . Since then, he has had his cartoons published in Folha de Sao Paulo, Brazil’s largest newspaper.
