(CNN) -- Authorities were hunting Tuesday in Kentucky for three escaped convicts who were considered armed and dangerous after guns were stolen during a home-invasion robbery.
Authorities had no new leads in their search Tuesday. But investigators said Monday that unconfirmed sightings had placed Christopher Marshall, Jerry Sargent and Bobby Cockerell in northern Kentucky, three days after they had broken out of the Branchville Correctional Facility near Tell City, Indiana, about 80 miles west of Louisville.
They were suspected of stealing a truck from a town near the prison and robbing three brothers in Sanders, Kentucky, about 65 miles east of Louisville, early Monday. The brothers were attacked, bound and held in their home for about an hour and a half while their assailants made off with guns and money, Kentucky State Police said.
"The three men left the residence with a sizable amount of cash and 10 guns of various types and calibers," State Police Capt. Dean Hayes said in a statement. "Also taken from the residence were several pairs of flannel shirts and jeans."
Police were looking for a dull-green 1998 Ford Ranger pickup in the case.
One of the three brothers was hospitalized after the encounter, while the other two were treated and released, Kentucky State Police said.
Marshall, 49, was serving a 50-year sentence for dealing cocaine, said Nick Zellers, a spokesman for the prison. Sargent, 59, was serving a 50-year term on robbery and criminal confinement charges, and Cockerell, 31, was serving a 20-year term for burglary, Zellers said in a statement.
Marshall and Sargent had been working in the welding shop, Zellers said. The convicts attacked a maintenance worker at the Indiana prison before breaking out, but investigators had not determined how they got out of the prison, he said.
