The Missouri governor’s office says it can’t appoint a special prosecutor to reopen the investigation into the fatal police shooting of Michael Brown, despite pressure from Brown’s mother.

Lezley McSpadden has launched an online petition seeking a new investigation into her son’s 2014 death in Ferguson. The case helped spark the Black Lives Matter movement.

Republican Gov. Mike. Parson’s spokeswoman said Friday that the governor “has no legal authority to appoint a special prosecutor in any case.”

Brown was 18 and unarmed when he was fatally shot during a confrontation with officer Darren Wilson on Aug. 9, 2014. Brown was black. Wilson, who is white, was cleared of wrongdoing and resigned that November.
