In Flint, Michigan, all charges were dropped against the state officials who made the disastrous decision to change thesource of the city’s water supply, to save money. 

The Michigan solicitor general, Fadwa Hammoud, who took control of the investigation in January after the election of a new attorney general, said “all available evidence was not pursued” by the previous team of prosecutors.

“This week, we completed the transfer into our possession millions of documents and hundreds of new electronic devices, significantly expanding the scope of our investigation,” Hammoud and the Wayne county prosecutor Kym Worthy said in a statement.

Our team’s efforts have produced the most comprehensive body of evidence to date related to the Flint water crisis. We are now in the best possible position to find the answers the citizens of Flint deserve and hold all responsible parties accountable,” they said.

They said it’s possible that Lyon and others could be charged again.

Flint was one of the worst manmade environmental disasters in US history. While waiting for a new pipeline to bring water from lake Huron, the majority-black city of 100,000 pulled water from the Flint River without treating it to reduce corrosive effects on old pipes. Lead infected the distribution system in Flint, where 41% of residents are classified by the government as living in poverty.
