BIRMINGHAM, Alabama – A jury this afternoon found Justin Jones guilty of reckless murder in the 2013 shooting death of a 15-year-old boy at Birmingham's Railroad Park.

The eight-woman, four-man, jury deliberated about four hours today after getting instructions on the law from Jefferson County Circuit Court Judge Clyde Jones and listening to closing arguments from a defense attorney and both prosecutors. Testimony in the trial had begun on Tuesday.

Judge Jones set the sentencing of Justin Jones in the case for Sept. 25. He faces a possible sentence of 20 years to life.

Deputy District Attorneys Danny Carr and Deborah Danneman prosecuted the case. Attorney Charles Salvagio defended Justin Jones.

Justin Jones was charged in the March 17, 2013 shooting death of Jermaine Walton. The only witness to step forward - out of up to 800 in the park that night - and testify said that Jones had "wildly" fired shots into the crowded park. Prosecutors said that Walton was an innocent victim.

The case came down to the credibility of that witness, who was the only one out of hundreds in the park that night to step forward to say they saw who shot Walton.

Walton's aunt, Patricia Pickett, said after the verdict that she hopes more young people are brave enough, like the witness in this case, to step forward and become witnesses to crimes in Birmingham. "If you see something you need to come forward," she said.

Pickett said two lives were lost because of the shooting -Walton's and Jones'.

Jones' family can still visit him, but her sister can only visit Walton's grave, Pickett said.

Salvagio said Jones was "stoic" after the verdict. Salvagio said he thought there might be a hung jury. He said the jury obviously believed the eyewitness in the case.

Carr said prosecutors appreciate jury's work and attentiveness during the trial and their verdict. "We hope this helps the (Walton) family," he said.
