(SALEM, IL) — After less than three hours of deliberations, Marion County jury found a 50-year-old Sandoval man guilty of First Degree Murder this afternoon, with the prosecution quickly filing a statement of intent to have the defendant declared a habitual criminal. Johnnie Mack will remain in custody of the Marion County Jail until sentencing for the November 2014 shooting death of 45-year-old David Harris, of Wamac, a crime for which Mack could receive a sentence of life in prison. A June 2, hearing was scheduled to hear the motion on the prosecution’s statement to have Mack declared a habitual criminal, which would allow for a life sentence.The jury received the case just before 11 a.m. Wednesday, with only one alternate being released, as the other alternate was seated Tuesday to replace a juror who had become ill. The guilty verdict was returned around 1:30 p.m.
