Neighbor Ayanna Williams was in shock that a 3-year-old was shot right on her block.
"I heard this big boom, so I'm like, 'I hope a car didn't run into nothing,'" she said. "I thought I was dreaming...I ran outside, and there were bodies out here."
Just hours later, around 7:25 p.m., at least 50 shots were fired into a crowd of about 30 people celebrating a high school graduation.
"You have a family that is gathering to celebrate the advancement of one of their kids having graduated high school and they have to suffer this," said Inspector D. F. Pace with the Philadelphia Police Department.
Police say two gunmen came around the corner at 59th Street and Lansdowne Avenue and shot three people attending the party just before 7:30 p.m.
