Ferguson activists targeted for killing?

In connection with this piece of news about the unexplained, gruesome murder of esteemed 75-year old African-American historian and civil rights activist Sadie Roberts-Joseph, I happened upon a tweet that mentioned that she is one in a series of several activist organisers of the Ferguson demonstrations found killed.

Tributes are pouring in for Sadie Roberts-Joseph, a prominent African-American historian and civil rights activist whose body was discovered in the trunk of her car in Baton Rouge, Louisiana, on Friday. Authorities said Monday the cause of death was homicide by asphyxiation, though few other details are known.

A string of deaths of prominent Ferguson activists and their relatives, as well as others who were murdered in a similar fashion, has left lingering questions about the circumstances. Given the recent detainment (with no justification given) of Iranian state TV journalist Marzieh Hashemi, who was working on a documentary about the murders, it’s worth re-examining the existing cases. We couldn’t find a comprehensive list placing the cases side-by-side, so we put this together. Some of the victims were notable figures in the protest movement, while others are related tangentially or by the strange nature of their deaths.
