MADISON, Wis. (AP) -

The Wisconsin Supreme Court is hearing the appeal of a Minnesota man convicted to killing a father and his teenage son at their La Crosse camera store in 2012.

Jeffrey Lepsch, of Dakota, Minnesota, contends his constitutional rights were denied because the jury selection process was flawed in his La Crosse County trial for the shooting deaths of Paul Petras and 19-year-old A.J. Petras at May's Photo.

The 4th District Court of Appeals ruled last year that Lepsch should have objected to the jury selection process at the time and the trial judge reasonably decided the jurors were impartial.
