DETROIT (AP) – A Pittsburgh-area official accused of obstructing police at a Detroit hotel will face a second trial in April on the felony charge. A jury in November couldn’t reach a unanimous verdict in the trial of Chelsa Wagner, the elected controller in Allegheny County. She was acquitted of disturbing the peace, a separate misdemeanor. Wagner, a Democrat, was accused of interfering with police as officers tried to remove her husband from the Westin Book Cadillac hotel last March. They were in Detroit to attend a concert. A judge set a new trial for April 20.
