LOUISVILLE, Ky. (WDRB) -- A Jefferson County Circuit Court judge on Wednesday morning denied shock probation for a man convicted of killing a witness in a Louisville murder trial.

Last year, 21-year-old Steven Pettway was convicted of killing Troya Sheckles in Shelby Park in 2009.

Sheckles was set to testify against Lloyd Hammond when she was shot and killed in broad daylight.

Pettway is now serving 55 years in state prison. Since he was a juvenile when the murder was committed, he was eligible for probation.

But Judge Angela McCormick Bisig closed that door for him on Tuesday morning. Pettway entered the courtroom wearing orange prison garb and glasses.

His attorney admitted that it was "awkward" that Pettway was asking for shock probation, even as he was appealing his case, adding that "he is not an aggressive person" and that he maintains his innocence. She asked the judge to remember that he was only 16 years old when the crime took place, and that he came from a broken home with an absent mom.

"He's one of the smartest people I've ever met," she said.

Prosecutors argued that "this a case where Pettway ran through a park to deliberately shoot Sheckles," and that, "if he was that smart he should have known" not to commit the crime.

Judge Bisig agreed, arguing that Pettway's sentence fit the crime, and that he should not be granted shock probation.
