At the vigil for Witherspoon on Sunday, some women sobbed while men wearing shirts bearing "R.I.P. Spoon" and "Whitelock" cried more quietly. At one point, a woman began to sing a hymn, while Witherspoon's mother joined in. Witherspoon had been pronounced dead at the scene Friday, and loved ones marked the spot on the street where he was shot, still bloodstained, with lit candles. A few in the crowd released heart-shaped balloons saying "I love you" into the sky.

Witherspoon's criminal record includes convictions for robbery and selling and possessing drugs, court records show.

"It's time for the madness to stop," said Edward Walker, Witherspoon's uncle. "Peace don't cost you nothing, respect don't cost you nothing. In this day and age, it's gone."

The weekend's shootings also included, according to police:
