CLEVELAND, Ohio -- A 20-year-old gang member charged with executing a teenage girl he and another man recruited to rob a bank was outed by his own mother, prosecutors told a jury on Tuesday.

Kiechaun Newell and Jeffrey Doss feared that 17-year-old Breanna Fluitt would "rat them out" after surveillance stills of her appeared in news outlets in connection to the Summit County bank robbery. They killed her to keep her quiet, Assistant Cuyahoga County Prosecutor Brian Kraft said.

But it was Newell's own mother who went to police in the days after the girl's death and said she suspected her son was involved, because he "had been bragging to them about what he had done," Kraft said.

Kraft told jurors during opening statements Tuesday that Newell's family members are among several people expected to testify during his trial on charges including aggravated murder, kidnapping, robbery. Newell faces a maximum of life without a chance at parole if he is convicted.

Doss will face the same charges in a separate trial.

Doss and Newell are members of the Black Disciples, an off-shoot of the Gangster Disciples gang, Kraft said.

Newell shot Breanna at Doss's behest, after authorities released surveillance photographs showing her robbing a Northfield Village bank on Aug. 15, 2016, prosecutors said.

The men had recruited the girl, who was a friend of Newell's, to carry out the robbery, Kraft said.

Doss and Newell "freaked out" and feared that Breanna was the weakest link in their operation and would rat them out, Kraft said.

So Doss ordered Newell to "get this girl up through," street slang for taking her life, Kraft said.

Newell agreed, and he and three teenagers picked her up on Aug. 19, 2016 in a stolen SUV, Kraft said.

Breanna sat in the backseat with Newell, and the two made out as the group rode around, "knowing that he was about to put five bullets in her," Kraft said.

The SUV pulled up to an empty parking lot on East 133rd Street near Hayden Avenue, Kraft said. Newell interrupted the make-out session, asked the driver to stop and suggested that everyone switch spots in the vehicle, Kraft said. When Breanna got out to walk around to the front seat, Newell pulled a pistol and shot her twice in the back, he said.

Newell and the boys then jumped back into the SUV and started to drive off, but Newell told them to stop again, jumped out and shot the girl three more times as she lay on the ground, Kraft said.

He jumped back into the SUV and they sped away, Kraft said.

A State Highway Patrol trooper stopped the SUV later in the evening when the tags came back to a stolen car, and the teenagers ran from the car, Kraft said.

The trooper spotted blood in the SUV, Kraft said.

The three teenagers were eventually caught and prosecutors gave them a deal that allowed their cases to stay in juvenile court in exchange for their testimony against Doss and Newell.

They are all expected to testify and identify Newell as the gunman, Kraft said.

Prosecutors also plan to play a recording of a police interrogation in which Newell confessed to the killing to East Cleveland police, Kraft said.

Newell, who has been jailed on $1 million bond since his arrest, denies the accusations.

One of Newell's lawyers, Brian McGraw, told jurors to keep in mind the deals that the teenagers got in exchange for their testimony, and question their motives.

"They have the type of motive to take guns out of their hands, put somebody present at a scene that wasn't there," he said.

Testimony resumed after lunch and is expected to last through next week.
