KANSAS CITY (AP) – Kansas City police are vowing to find the person or persons responsible for the shooting death of a 6-year-old girl while she was at a convenience store with her dad.

Hundreds of people turned out Sunday evening to remember Angel Hooper and call for justice in her shooting. The girl died Friday evening after being shot at a south Kansas City convenience store. Angel and her father stopped at the store for bubblegum when someone in a passing car shot at them.

Maj. Karl Oakman, commander of the police department’s South Patrol Division, said Angel has “all the power of the Kansas City Police Department behind her.”

The Kansas City Star reports that Angel’s mother, Charity Guinn, said she is confident officers will make an arrest.
