It was clear by the love expressed in a Conyers church Saturday night that the memories of Jarmecca Yvonne Whitehead, or “Nikki” as she was nicknamed, have not diminished more than a year after her death. About 40 of her friends and family members gathered at HighPointe Church on Highway 138 for a memorial service. Originally planned for the one-year date of Nikki’s death on Jan. 13, it was rescheduled because of the snow.
