Jury finds gunman guilty in murder of 9-year-old Tyshawn Lee

CHICAGO (WGN) -- A jury has convicted a man of first-degree murder in the shooting death of a 9-year-old Chicago boy who was lured into an alley with the promise of a juice box.

Prosecutors contended that Dwright Boone-Doty and fellow gang member Corey Morgan planned the November 2015 slaying of Tyshawn Lee before Boone-Doty took a gun Morgan gave him and shot the boy.

The Cook County jury found Boone-Doty guilty on Thursday night. A separate jury deciding Morgan's fate has been sequestered after not being able to reach a verdict.

Earlier, prosecutors asked jurors to convict Morgan in the shooting death of Tyshawn Lee. They allege that Morgan and a fellow gang member accused of pulling the trigger, Boone-Doty, carried out the killing because they believed the boy's father was in a gang that killed Morgan's brother weeks earlier.

Morgan's attorneys say he had nothing to do with the killing and that he was targeted by police because he was a gang member whose brother had recently been killed.

For a separate jury, prosecutor Patrick Waller described how Boone-Doty executed Tyshawn with a 40-caliber handgun.

“That word executed really doesn't do justice to what happened,” he said. “Unfortunately, you got to see what happened to Tyshawn Lee.”

During the three-week trial, jurors had seen graphic photos of the boy's lifeless body lying on a slab with multiple gunshot wounds at the medical examiner's office.
