The Karen L. Johnson DMV in Minqaudale opened its doors on Tuesday morning, taking customers by appointment only.
It was in that building, on December 23, that Corporal Matthew Ty Snook was killed while working an overtime shift.
Those who knew Corporal Snook say his memory lives on there.
"His presence will be missed, because he was such a great officer, he was, he was such a great officer. Today is a great day to continue to move on," said Kareema Crawford.
