密歇根新闻广播 科学分歧可能影响检察官对弗林特水危机的调查（在线收听）

A Flint water researcher might have thrown a monkey wrench into prosecutors' case against Nick Lyon, director of the Michigan Department of Health and Human Services. Lyon is being prosecuted by the state on charges of involuntary manslaughter and misconduct. Another agency official is charged with obstruction of justice.

The wrench: a complaint lodged by Virginia Tech professor Marc Edwards, the researcher who first came forward with evidence that Flint had elevated levels of lead in its drinking water.

Edwards is challenging the veracity of the research of another Flint water researcher, Shawn McElmurry, who is a key witness in the prosecution’s case against Lyon.

Michigan Radio reporter Steve Carmody joined Stateside to recap Mark Edwards’ connection to Flint, his complaint against McElmurry’s research, and what it means for Attorney General Bill Schuette’s special prosecutor’s case against Lyon.

Peter Henning, a Wayne State University law professor and former federal prosecutor, also joined Stateside to discuss how the complaint — and Mark Edwards’ popularity in Flint — could affect the prosecution’s strategy.
