Aknife was also found on the ground near his body.“Well, my brother is harmless," said Darryl Daniels, the victim's brother. "He’s harmless and he wouldn’t have hurt her. He wouldn’t have hurt nobody. She just didn’t know him. Because if she’d have known my brother, she’d have known that 'Poochie' wouldn’t have hurt nobody.”The brother said he didn’t believe Daniels knew the shooter and that he was most likely at the store buying a pack of cigarettes before planning to catch the bus.The woman fled the scene, but a witness recorded her license plate number, which was given to police.Police tracked her down and took her in for questioning.
