On Tuesday the little boy would have been two years old. A week ago Saa-sean, his mother, Samara Banks, and his two brothers were struck and killed on Roosevelt Boulevard near 2nd Street.
"He had a long long life ahead of him, but apparently God wanted him and the boys and Samara," said the boy's father, Sean Williams.
Near the same spot where police say a street racer ran down the mother and her boys, family and friends hugged each other and brought birthday balloons in honor of Saa-sean.
"Saa-sean was a quiet happy silly little boy," said his grandmother, Donna Day.
Since the tragedy, local social and auto clubs have been on the boulevard collecting donations for funeral arrangements and for a trust to benefit Banks' surviving 5-year-old son, Saa-yon Griffin, who is still recovering from his injuries.
"I can't imagine waking up at that age and your mom not being there and your siblings not being there," said Arvella Love of North Philadelphia. "So this is a child that has to survive with the support of the remaining family. And the community has decided, in a way, to adopt this child."
People signed a petition asking the city to make this stretch safer for pedestrians.
Moments later, Saa-sean's family, including his father, sang 'Happy Birthday' to him and released those balloons into the air.
"I just want to say, 'Happy Birthday' to my baby boy, Saa-sean Williams," said his dad. "And he will be greatly missed and always in my heart.'
