MADISON, Wis. (AP) -- A spokesman says the Wisconsin Department of Justice has opened a perjury investigation into an expert witness who lied about his credentials in a high-profile homicide case.
Spokesman Kevin St. John says the agency is acting as special prosecutor in the case involving discredited injury expert Saami Shaibani of Lynchburg, Virginia.
Shaibani was a key witness in the 2002 first-degree intentional homicide trial of Douglas Plude, a northern Wisconsin man accused of poisoning his wife and drowning her in a toilet bowl.
Plude was convicted and sentenced to life in prison, but the Wisconsin Supreme Court ordered a new trial in June after evidence showed Shaibani lied about being a professor at Temple University.
Shaibani has not returned multiple phone messages for comment.
