ATLANTA (AP/WAOK) – A metro Atlanta woman convicted of vehicular homicide in the jaywalking-related death of her 4-year-old son has lost an appeal.

Officials say the next step for Raquel Nelson is to take her case to the Georgia Supreme Court.

In her appeal, defense lawyer Steve Sadow maintained that the Cobb County Solicitor’s Office presented insufficient evidence to prove she was criminally responsible for the death of her son A.J. Newman in April 2010 in Marietta.

But Appellate Judges Charles B. Mikell, M. Yvette Miller and William M. Ray II disagreed.

Nelson was charged after A.J. was struck by a van as they jaywalked across a busy five-lane road, and the case sparked outrage from activists who gathered thousands of signatures on an online petition to support her.
