The portrait was created by Officer Jonny Castro, the police department's new forensic graphic artist.
This Saturday marks one year since Sgt. Wilson was killed at a North Philadelphia GameStop store. He went in to buy his young son a gift when he was gunned down as he tried to stop a robbery.
Police say his bravery and courage saved the lives of others inside the store.
After viewing surveillance video of the shootout, former Philadelphia Police Commissioner Charles Ramsey said "I've been in policing for 46 years and I have never witnessed an act of bravery like I saw that day - never."
Officer Castro says, "March 5th will mark the 1 year anniversary of Sergeant Robert Wilson's murder. I painted this portrait of him in remembrance of what he did for us all."
