As expected, the fourth man accused in the armed robbery and murder of marijuana businessman Sam Simko in January will join his three co-defendants for a preliminary examination on May 30.

At a court hearing Tuesday, 50th District Judge Cynthia Walker scheduled Christopher Matacia for the exam, which will be held to determine if the cases against him and the others — Scott Brown, William Creasy and Deonte Prophett — will proceed to Oakland County Circuit Court for possible trial.

Simko, of Commerce Township, was fatally shot on Jan. 13 at his cannabis grow facility in the 1000 block of University Drive in Pontiac. He was 66.

Approximately 50 pounds of marijuana was stolen, according to the Oakland County Sheriff’s Office.
