The grand jury, which last met on Friday, will reconvene Monday, federal and local law enforcement officials told CNN.
So, frustrated residents will have to wait a little longer to hear whether Wilson, who is white, will face charges in the August 9 shooting death of unarmed 18-year-old Michael Brown, who was black.
That was deeply disappointing to Brandon Turner, 25, who works at a barber shop on West Florissant Avenue, ground zero for the protests after Brown was shot multiple times.
"I just think this is crazy," he said. "A young man was killed on the street in broad daylight. I am surprised it has taken so long. I've got a lot of clients and they're all in shock."
Cipriano Medina, a 39-year-old architect who was visiting friends in Ferguson on Saturday, said waiting longer would be worth it if the grand jury was getting more pertinent information to consider.
