On October 3, 2002, 25-year-old Lori Ann Lewis Rivera was shot and killed while vacuuming her burgundy minivan at a Shell gas station in Kensington, Maryland. A native of Idaho who had moved to Maryland to work as a nanny, she was a mother to a preschool-aged daughter. Her death was one of ten during a three-week series of sniper-style shootings that terrorized the Washington metropolitan area.

The killings were carried out from the trunk of a modified Chevrolet Caprice by two perpetrators who were later apprehended. The capture of those suspects ended the immediate threat to the region and led to prosecutions in connection with the shooting spree. If anyone knew Lori, her movements that day, or witnessed activity at the Kensington Shell station on October 3, 2002, please come forward with information.
