A nationwide manhunt is underway for two Georgia inmates who allegedly shot and killed two correctional officers before escaping in a Honda Civic early Tuesday, according to police.

Donnie Russell Rowe, 43, and Ricky Dubose, 24, allegedly overpowered two state correctional officers who were driving a bus transporting inmates, officials said during a press conference. Police said the fugitives then allegedly carjacked a “grass green” four-door Honda Civic and fled the scene.

The bus was on Georgia Highway 16 between Eatonton and Sparta, about 75 miles south of Atlanta.

The Georgia Department of Corrections later identified officers Christopher Monica, 42, and Curtis Billue, 58, as the two officers who were shot and killed. Monica had been with the force for more than seven years and Billue had served for nearly a decade, according to police.
