The Ferguson, Mo., grand jury considering the indictment of Officer Darren Wilson, who killed teenager Michael Brown during an altercation in August, left the justice center in St. Louis on Friday without reaching a decision.
Sources told CNN on Saturday that it was unclear when the jury would reconvene.
Local business owners are bracing for more looting and vandalism.
Natalie DuBose, owner of Natalie Cakes and More in Ferguson told CNN she has had fewer customers in anticipation of the jury’s decision.
“If I can’t open my doors every morning, I can’t feed my kids in the evening,” said Ms. DuBose, a mother of two said, and asked protesters to spare her shop, the network reported.
