Inside the 22nd District police station where Sgt. Robert Wilson III once worked, hundreds gathered to honor the man who sacrificed his life to protect innocent civilians.
Colleagues and family members spoke, including Sgt. Wilson's sister, Shaki'ra Wilson-Burroughs. She was wearing a shirt with her brother's badge number, 9990.
"I miss him every day. Four years is the longest I haven't spoken to him. It's hard," she said.
Outside 22nd District, balloons were released in Sgt. Wilson's honor.
His two sons were not at the ceremony.
On March 5, 2015, then 30-year-old Wilson was inside the Gamestop store at 21st Street and Lehigh Avenue to buy a birthday present for one of his sons when two armed men attempted to rob the place. Gunfire was exchanged, Sgt. Wilson was shot multiple times and was killed.
He is credited with shielding customers inside.
"Its so important for us to be here irregardless of the passage of time. Over the years, we have to be here to show them that we care and that we will always be here to wrap our arms, both literally and figuratively, because we are one big family. And when I say that, I don't only mean people who wear this uniform. I talking about this community," Ross said.
Sgt. Wilson's plaque joins two others at the district, serving as a reminder of the dedication and service of the men and women in blue.
