Shouts of protesters are filling Cincinnati's Fountain Square as hundreds of people demand the immediate retrial of University of Cincinnati Police Officer Ray Tensing, whose murder trial in the death of unarmed motorist Sam DuBose ended in a mistrial Saturday.

In the video below, members of the DuBose family -- Chyna DuBose-Reid and DaShonda Reid -- talk with members of the media after a mistrial was declared in the trial of Ray Tensing.

Hamilton County Prosecutor Joe Deters, speaking for the first time in several days after the judge overseeing the case lifted a gag order, revealed the jury voted eight to four in favor of a voluntary manslaughter conviction.

At least three jurors were willing to find Tensing guilty of murder, Deters said.

Upset by the hung jury, scores gathered outside of both the Cincinnati City Hall and the Hamilton County Courthouse and began marching through Downtown. They chanted sayings such as "Whose streets? Our streets!" and "The whole damn system is guilty as hell."

Several held signs bearing messages declaring Tensing's guilt. One read: "The only thing killer cops will understand is jail time." Said another: "Ray Tensing is a murderer."

"We demand an immediate retrial," Ashley Harrington of the advocacy group Black Lives Matter: Cincinnati told a group gathered outside of the courthouse.

Whether that will happen remains a question mark. As requested by Judge Megan Shanahan, Prosecutor Joe Deters said he hoped to decide within two weeks whether to charge Tensing again.

The prosecutor said that eight of the 12 jurors were willing to convict on a charge of voluntary manslaughter, and three were in favor of a murder conviction.

As the crowd grew, it began to block traffic on Main Street. Cincinnati Police officers worked to keep the thoroughfare clear as the marching began by asking people to stay on the sidewalks.

That group converged with another cluster of protesters Downtown -- those protesting the outcome of Tuesday's presidential election, won by businessman Donald Trump. The two groups broke through a police line at Court Street and marched in tandem for a bit, clogging Walnut Street for about two blocks en route to Fountain Square.

Chants of "They go low, we go high" -- a refrain First Lady Michelle Obama made in campaign speeches supporting failed Democrat nominee Hillary Clinton -- morphed into "Hands up, don't shoot" -- a mantra used in Black Lives Matter protests nationwide for more than two years.
