According to the Web site savekevincooper.org, a statewide "day of action" has been scheduled for Tuesday to protest Kevin Cooper's scheduled Feb. 10 date with death.
Cooper was convicted in 1985 of the massacre of two adults and two children in a Chino Hills home where San Bernardino County authorities said he had been hiding after escaping from a nearby prison.
Cooper and his supporters claim he is innocent and was railroaded because he is African American and was the victim of planted evidence.
Gov. Arnold Schwarzenegger last week refused a clemency hearing, saying he had seen no compelling evidence to support claims of police misconduct, and pointed to recent DNA tests that placed Cooper at the crime scene.
