CHICAGO -- The family of a infant gunned down in Chicago wants answers and justice.

Five bullets hit six-month-old Jonylah Watkinsall while her dad changed her diaper in the front seat of their minivan.

Surveillance video shows the gunman get into a blue car and speed off right after the shooting.

The family is outraged and wants someone held responsible.

"Please, whoever did this turn yourself in," said Jonylah's aunt, Erica Young. "My niece didn't do anything wrong. I don't understand why someone would do this. I don't know."

Police believe it is gang related and that the shooting targeted Jonylah's dad.

He is in the hospital with serious injuries.
