In 2008, a protester who had been participating in the demonstration was arrested and accused of killing Will. He was released in 2010 after a federal appeals court cleared him in the killing.

Will, a 36-year-old documentary filmmaker who had been living in New York, was among three people killed when gunmen opened fire on teachers who were protesting against the government in the southern state capital of Oaxaca.

He was covering the resistance by teachers and other workers who had protested for months in Oaxaca, barricading streets, occupying government buildings and calling for the governor to be ousted.

Will was shot in the stomach and died before reaching a Red Cross station.
