Officer Robert Wilson III was killed in the line of duty, protecting others while trying to stop a robbery in 2015.
"I feel as though my brother should still be here, I feel as though he still is here," his sister, Shaki'ra Wilson-Burroughs, said Thursday at the fifth anniversary of his death.
Wilson's friends, family and former colleagues gathered in front of his district building, 22nd District, in North Philadelphia for a memorial service honoring him.
She says they want to continue Wilson's work in a meaningful way to the communities he serviced.
"The vision for this foundation is to encapsulate and personify everything that mattered to Robbie. This foundation will provide educational, charitable, and community-based programs and services," she explained.
Wilson was 30 when he died. He left behind a son and a daughter.
