One has pled guilty and one is on trial this week... that's John Little and Cidney Ingram, who are believed responsible for the death of Jason Williams, who was found shot to death outside of an apartment complex along the 31-hundred block of Electric Avenue in Port Huron in June.  Little has entered a guilty plea for tampering with evidence, as well as accessory after the fact to murder, according to officials with St. Clair County Circuit Court.  He's set for sentencing on January 7th.   Meanwhile, a jury has been seated and a trial is now underway for Ingram, who's charged with open murder.
