The inmates were being hunted in the killings Tuesday morning of two prison guards who were overpowered, disarmed and shot to death on a prison bus in Putnam County.
Authorities are now conducting a nationwide search for Ricky Dubose and Donnie Rowe.
"The caller said men that matched the description were going in and out of the woods and looked suspicious", Malphrus said. Later the prisoners stole a white Ford F-250 from a locked quarry at approximately 11 p.m.
Putnam County Sheriff Howard Sills said earlier on Thursday that the public was in "grave danger" and that authorities did not know where the inmates were. "These are seriously unsafe, vicious hoodlums that need to be apprehended". 'I've worked in law enforcement in this state in some capacity for 44 years and I can tell you today, there has never been a reward that large, ' Sills said, FBI Atlanta Special Agent in Charge David LeValley said people throughout the state and country should be looking for the inmates.
After killing the guards and fleeing the prison bus, Rowe and Dubose carjacked a driver who had pulled up behind the bus.
"It's very frustrating", Sills said.
Sills said it was hard to determine if the two men were being helped by anyone on the outside but said there were an infinite number of possibilities since both men have friends and family in the area. He had served almost eight years for the department.

"They brutally shot those officers multiple times", Sills said.
Update 9 p.m. ET Authorities say both men were apprehended after a auto chase in Murfreesboro, Tennessee. "They would do a crime and it would escalate".

Both escapees were serving sentences for armed robbery and other crimes. Monica had been with the Georgia Department of Corrections since October 2009 and Billue since July 2007.
Authorities said the inmates were being transported when they overpowered the two officers, one of whom was driving the transport bus.
Rowe is serving life without parole for armed robbery and Dubose is serving a 20-year sentence for armed robbery, according to the Georgia Department of Corrections. "It's a shame two individuals would be so cowardly to do this", Dozier said.
