ALEXANDRIA, Va. (WUSA9) -- The jury deliberated for just over a day to find 45-year-old Craig Patterson guilty of voluntary manslaughter.
He was found not guilty of using a firearm in commission of the murder. The former Arlington County Sheriff's Deputy shot and killed 22-year-old Julian Dawkins last May.
Patterson dealt with inmates for nearly his entire career as an Arlington County Sheriff's deputy now finds himself a convicted felon.
Gwen Pratt Miller says she lost her son for no good reason.
22-year-old Julian Dawkins, a shuttle driver for PBS aspired to own his own auto detailing business. But those dreams were cut short when Patterson shot and killed the young man last May.
Curtis Dawkins, the father says, "I'm numb at this point. Something needs to be done in reference to these types of crimes, not just for my son but for others victims."
Dawkins was celebrating his cousin's news of making it to the WNBA.
The defense says Dawkins was drunk when he chased Patterson with a knife. They say sheriff's deputy was acting in self defense.
Prosecutors say the veteran officer should have called 9-1-1 but instead left to get his gun, badge and handcuffs.
The jury is now deciding on Patterson's punishment at this hour.
Patterson faces anywhere from a $2500 dollar fine and or maximum 10 years in prison.
