A minor charged with killing a young man after his high school graduation ceremony in Fairfield may be tried as an adult following a petition from the Solano County District Attorney’s Office.

On Tuesday, 17-year-old Khare Clark appeared in juvenile court to plead not guilty to charges of murder and several counts of attempted murder in the shooting death of 18-year-old Jamario Baker. On June 3, Clark allegedly opened fire in the parking lot of Sem Yeto High School following the school’s graduation ceremony.

An 11-year-old and two adults were also injured in the shooting. Around 1,000 people attended the ceremony, according to the district attorney’s office.

Clark was arrested in Texas in July following a monthlong investigation and was extradited to California for trial.

A hearing date to transfer Clark to adult court will be set at a proceeding scheduled in September.

According to the district attorney’s office, Clark will be transferred to adult court “if and only if” it is decided he will not be rehabilitated if placed under the authority of juvenile court.
