Murder of CEO is Basis for Riverside County Mock Trial Student Competition

RIVERSIDE – The murder of a chief executive and the revelation of a plot to commit corporate fraud, represent the basis for the fictional trial, People vs. Clark, which Riverside County students from 22 high schools will adjudicate throughout January and February at the 42nd Annual Riverside County Mock Trial competition organized by the Riverside County Office of Education.

Mock Trial involves students arguing cases in front of real judges, while being scored by practicing attorneys. The competition is open to all students in grades 9 through 12 enrolled in public and private high schools in Riverside County. Teams consist of 8-25 students filling the courtroom roles of defense and prosecution attorneys, witnesses, clerks, and more.

Attorneys, judges, and legal professionals from across Riverside County are among the 14,000 students who have participated in Mock Trial now in its 42nd year of competition. The month-long competition is sponsored by Riverside County Superior Courts, the Riverside County Bar Association, and the Riverside County Office of Education.

The fictional case materials provide the facts and legal background for this year’s trial, People v. Clark. Sunshine Medical Components (SMC) Chief Executive Officer, Kieran Sunshine, was found murdered in a hotel room with apparent stab wounds from a small saber used to open champagne bottles. A plot to commit fraud against the SMC board of directors surfaced, and the prosecution believes this was a motive for the murder. However, multiple executives at SMC—both of whom are family members of the deceased chief executive—may also have had motive or involvement. A review of the forensic evidence, collection techniques, and the legality of technology-focused warrants, will contribute to the fictitious trial.

The opening rounds will take place on Thursday, Jan. 25, in three locations across Riverside County (first team listed is prosecution, second team is defense):
