Richard Groff says his brother was a jokester who loved to laugh.

“It was the great part about him, it really was,” he said. “I mean, every moment that I got to spend with him before he went to Philly, it was awesome. I tried so hard to keep him from all the troubling things in life, but it just didn’t work out that way.”

The Center City District is adding 20 unarmed, uniformed bike patrols in the area around LOVE Park. They were planned before this incident to make people feel safer as they return to work.

Mayor Jim Kenney says despite this incident and others, Center City is safe.
