Officials doubled the reward to $200,000 recently for the arrest and indictment of seven fugitives still on the run from a Texas prison. They also said a leaked memo detailing the escape had been misconstrued and that supervisors had never left the inmates alone.
Part of the memo describing an inmate “picnic'' during the lunch hour that preceded the Dec. 13 escape was inaccurately reported by the media, said Glen Castlebury, a spokesman for the Texas Department of Criminal Justice.
According to the memo, six inmates working in the maintenance department of the medium-security Connally Unit told their civilian supervisors they weren't going to the inmate dining room but planned to eat in the maintenance area.
Castlebury said media reports indicated the inmates were left alone when the supervisors left for their own lunch, when in fact a maintenance supervisor had stayed in the room.
A seventh inmate probably joined the others after the supervisors left, the memo said.
Castlebury said the inmates overpowered the remaining supervisor, then took the 10 civilian workers and a guard hostage one at a time when they returned from lunch, Castlebury said.
He said a report on the investigation of the escape would be released around the middle of this week. 
The memo was disclosed by KHOU-TV of Houston, which did not say how it obtained the document.
After overpowering the supervisors, the memo said, one of the inmates called a guard tower, pretended to be a prison supervisor and said he was sending a crew to work on surveillance equipment.
An inmate dressed in stolen civilian clothes then tricked the tower guard into letting him and three other inmates inside, the memo said. After they overpowered that guard, they had control of the tower, an armory and the prison gates.
All seven then were able to leave the prison in a truck they had loaded with provisions, 14 pistols, a rifle, a shotgun and more than 200 rounds of ammunition.
The fugitives are wanted on capital murder charges following the robbery of a sporting goods store in a Dallas suburb on Christmas Eve. Irving police officer Aubrey Hawkins was shot 11 times - six times in the head.
Authorities across the state had received more than 1,200 tips by January 6.
Officials doubled the reward for their capture in an effort to “entice those who are helping the inmates to turn them in to earn the cash,'' Texas Department of Criminal Justice spokesman Larry Todd said.
A recent broadcast of the crime TV show ``America's Most Wanted'' featured a story on the escapees and yielded 66 tips in the minutes following the program, hotline supervisor Jim Layton said.
