Officials are investigating, Sosebee said, but no criminal charges have been filed.
Sosebee said the other rider sustained minor injuries but was released from a hospital hours later.
Bell won a plurality in a special election earlier this year to become mayor of White, which is about 50 miles northwest of Atlanta. He sought to restore the mayor’s powers after many were transferred to a city manager and the previous mayor resigned.
Following Bell’s death, White Mayor Pro Tem Gary Crisp will take over mayoral duties. Crisp told Channel 2 Action News that it’s likely the city will hold another special election to replace Bell.
