Story highlights Jail is about 35 miles northwest of Birmingham 
 
 Inmates used peanut butter to trick guard and escape 
 
 (CNN) One inmate remains at large after a jailbreak Sunday night in northern Alabama, according to the Walker County Sheriff's Office. 
 
 Twelve prisoners went on the run from the Walker County Jail, in Jasper, the office said, but 11 have since been captured. 
 
 In a press conference on Monday, Sheriff James Underwood said the inmates used peanut butter to escape the facility. 
 
 The prisoners took advantage of a new guard who was working in the control room, Underwood said, using peanut butter to obscure the number above the jail cell and then yelling at the unidentified guard to open the door to let them in the cell. 
 
 "They changed the number over the door with peanut butter," he said. "(Then) they hollered, 'Hey, open door' so-and-so, but (the number the inmates gave the worker) was the outside door.

 Twelve inmates escaped an Alabama jail Sunday night after using peanut butter to cover a door number and trick a young jailer, Walker County Sheriff James Underwood said Monday. 
 
 Of the 12, all but one was back in custody by daybreak Monday. "I thank the Lord today we have 11 people back in the jail,'' the sheriff said. 
 
 Only Brady Andrew Kilpatrick, a Cordova man jailed for possession of a controlled substance,possession of drug paraphernalia, and possession of marijuana, remains at large. Underwood said he doesn't believe Kilpatrick is dangerous. 
 
 The Walker County jail break happened about 6:30 p.m. Sunday at the county jail in Jasper. The jailer opened a door to the outside thinking it was a cell door, Underwood said, because the number had been covered with peanut butter. 
 
 "Changing numbers on doors with peanut butter -- It may sound crazy, but these kinds of people are crazy like a fox." Underwood told a news conference. "He thought he was opening the cell door for this man to go in his cell, but in fact he opened up the outside door." 
 
 The dozen inmates then scaled a 12-foot fence topped with razor wire after walking out. Some were cut and scraped, but none seriously injured. He said it probably took them about 10 minutes to clear the fence. 
 
 "Escapes happen," Underwood said. "We've got some evil people down here, and they scheme all the time to con us and our employees at the jail. You've got to stay on your toes. This is one time we slipped up. I'm not going to make any excuses." 
 
 There were about 140 inmates in the jail Sunday. A staff of seven jailers was on duty. 
 
 After making their break, all 12 of the inmates met up at an undisclosed location about four miles from the jail. Not all of the inmates in the cell that had contained the inmates who escaped left, and were cooperative with deputies. "They helped us considerably,'' the sheriff said. 
 
 Once the jailer realized the inmates were gone, they took a head count to determine who was missing. Acting on information quickly developed, lawmen went to the location where the group had planned to meet and recaptured six of the escapees within 90 minutes - John Richard Hunter, 26, Christopher Cole Spain, 18, Kristopher Keith Secrest, 20, Quadrekas Latoddrick Key, 21, Timothy Chaz Cooper, 28, and Steven Sanford Hartley, 27. 
 
 Over the next eight hours, with the help of multiple law enforcement agencies, five more escapees were taken into custody: Michael Adam MicGuff, 30, Steven Blake Lamb, 28, Christopher Michael Smith, 19, Larry Inman, 29, and Ethan Howard Pearl. 
 
 One of the inmates was recaptured in Townley, where the sheriff said a car was stolen. Two others were captured by deputies and Birmingham police at the Flying J off of Interstate 65. 
 
 Underwood said all 11 inmates captured were still wearing their prison garb. 
 
 Authorities had offered a $500 reward for information leading to the recapture of the inmates. Underwood was asked about what some perceived as a low reward amount, but he said he felt it was adequate. "That's a lot to some people,'' he said. "We're going to pay a few people for their help." 
 
 Reward money will be paid out to several tipsters, he said. Other may face criminal charges for helping the inmates remain at large. "They had some outside help,'' Underwood said. "We will get to the bottom of it." 
 
 Underwood said there are two cameras at the jail, and both were working when the escape happened. The locks also were in working order. Though the jail, built 19 years ago, has its deficiencies, they didn't contribute to the Sunday debacle. 
 
 "I said it was human error and he made a mistake," Underwood said. "He's a young guy, he hasn't been there that long. This young man was a weak link, and they knew it." 
 
 Asked if the jailer would face disciplinary action, the sheriff said, "We're going to take care of that matter,'' he said. 
 
 He said the incident remains under investigation by his own department. They are not bringing in any outside agency to assist in the probe. 
 
 Underwood said there hasn't been an escape at the Walker County Jail in three years. "You a run a jail, you're liable to have escapes,'' Underwood said. "It's the cost of doing business."

– Peanut butter was the key ingredient in Sunday evening's mass escape from an Alabama jail, Sheriff James Underwood says. The sheriff says the 12 men escaped after using peanut butter to cover up a door number, AL.com reports. They then convinced a new guard in the control room to open the door, which led outside. "It may sound crazy, but these kinds of people are crazy like a fox," Underwood says. Because the door number was obscured by peanut butter, "he thought he was opening the cell door for this man to go in his cell, but in fact he opened up the outside door." The inmates, including two men accused of attempted murder, scaled a 12-foot fence topped with razor wire after making their way outside and escaped without serious injury. Underwood says the inmates took advantage of a "young guy" who hadn't been working at the Walker County Jail for long. "Escapes happen," Underwood says. "This is one time we slipped up. I'm not going to make any excuses." The sheriff says 11 of the 12 inmates have now been recaptured, CNN reports. Six were recaptured within 90 minutes and five more were caught by a manhunt over the next eight hours, including one inmate who'd apparently stolen a car and two who were at a convenience store on Interstate 65. The only inmate still on the loose is Brady Andrew Kilpatrick, 24. He was jailed for drug offenses including possession of marijuana; Underwood says he's not considered dangerous.
