PEORIA, Ill -- A Peoria man is on trial for murder this week on a cold case dating back to the Spring of 2004.
Robert Nunn Sr. is accused of executing Antonio Faulkner, while Faulkner sat sleeping in his car at a home on Wiswall Court.
Authorities say Nunn shot the victim in the head after the two had a fight the night before.
In their opening statements, Peoria County prosecutors called this a case of opportunity, solved only after several incarcerated eyewitnesses decided to break their silence last year.
Defense attorney Chuck Schierer told the jury his client is innocent, saying there is no physical evidence linking Nunn to the crime, and there are multiple, plausible explanations for Antonio Faulkner's death.
The state's witness testimony is expected to continue Tuesday afternoon.
