The sedan that caused the crash “lost control and stopped momentarily but then left the scene,” Campbell said.

Police are working to get footage from cameras in the area.

They are asking car repair shops and others to be on the lookout for a sedan with front-end damage.

“We really want to impress upon this driver to come forward,” Campbell said.

“If you see something that you’ve done wrong, stop. Help. It could have been an accident. But leaving the scene, it makes it worse.”

The DeKalb County School District made a similar plea.

“Our thoughts and prayers go out to the family, friends (and) school community, and we will assist in providing grief counseling and support,” district spokesman Andre Riley said. “We urge anyone with information about this event to contact the DeKalb County police, to ensure justice is served.”
