RIVERDALE, Md. - Students at Riverdale Elementary School returned to class Monday for the first time since two of their classmates were hit and killed near the school.
Family and friends of 10-year-old Shalom Mbah and 5-year-old Sky Sosa came together over the weekend for a vigil in their memory.
Both were killed when they were hit by a car on November 21.
Investigators are still working to determine if the driver should be charged but officials say that could take some time.
