PUTNAM COUNTY, Ga. -- Police and law enforcement officials from throughout the Southeast continue to search for two escaped inmates accused of shooting and killing two corrections officers in Putnam County on Tuesday morning.

A statewide manhunt has been underway since the incident, when authorities said Ricky Dubose and Donnie Russell Rowe were being transported on a bus when they allegedly overpowered the guards, killed them and escaped.

Veteran correctional officers Christopher Monica, 42, and Curtis Billue, 58, were killed in the incident.

The incident happened on Hwy 16 West of Sparta near Eatonton around 6:45 a.m. when there were 33 prisoners and two guards on the bus.

A local resident was driving along Hwy. 16 when he saw the stopped bus and mistakenly thought it was part of a work detail. When he stopped his car, police said the inmates robbed him at gunpoint. The driver was unharmed and flagged down the next car for help.

THE MANHUNT

The US Marshals Southeast Regional Fugitive Task Force, FBI and the Georgia Bureau of Investigation are involved in the search, along with several other agencies.

"We are searching everywhere in America,' said Sills. "They could be headed anywhere."

Sills said he doesn't know how the inmates were able to overpower the guards and kill them.

"I can't tell you how they got through the gate," Sills said, who added the guards were shot on the bus. "I still have their blood on my shoes."

During a 6:30 p.m. media briefing on Tuesday, Sills said the inmates broke into a home on Cox Road in Morgan County earlier in the day. The home was ransacked, Sills said, and Dubose and Rowe stole some food and clothes.

Morgan County Sheriff Capt. Christopher Bish said when the inmates broke into the home in Madison, they left their prison whites.

A tip lead investigators to a Family Dollar store in Madison. According to 11Alive's Faith Abubey, officers cleared the stores in the plaza. Some were seen headed into a wooded area nearby. Bish said there was a confirmed sighting at the store, but witnesses were unsure whether the inmates left in a vehicle or by foot.

"We do have confirmation that they were in the Family Dollar earlier this afternoon -- around 2:30ish -- and that's why we're doing the grid search both north and south of this location," Bish said.

However, Sills later said police have not confirmed they were in the store.

Heavily-armed law enforcement officers cleared the retail stores one by one along Eatonton Road, and then moved to search a nearby Budget Inn room by room.

According to the GBI, a $70,000 reward is being offered for information leading to the inmates' arrest.

Sheriff Sills had a message for the escaped inmates: "I would suggest you surrender before we find you."

According to the Georgia Department of Corrections, officers Monica, 42, and Curtis Billue, 58, were hired in October 2009 and July 2007, respectively.

Greg Dozier, Department of Corrections Commissioner, said the phone call about the deaths hit him hard: "My heart is still in the soles of my shoes."

Dozier said both officers leave behind families and described them as "great officers."
