The group estimates that Brazil is responsible for 44% of all homophobic murders in the world and the numbers from 2012 represent a 27% increase in murders from 2011.
According to the report, 188 gay men and 128 trans individuals — including 2 transsexuals killed in Italy — were murdered last year, with lesbians accounting for about 5% of all cases.
Of the 338 reported murders, only 89 assailants were found; the remaining 73% of cases saw no arrests.
Murder in the Brazilian trans community is particularly high as trans people are often forced into prostitution to make a living.
Grupo Gay da Bahia maintains that their numbers are not completely accurate since gay-related hate crimes are not always reported. Brazilian activists are calling for tougher hate crime legislation and for both homophobic and transphobic attacks to be treated as seriously as those motivated by race.
