The inmates may be behind bars, but some items still slip by security.
Now, jailers are getting some help in keeping some items out of their hands.
"We like to say we're protecting Daviess County from the inside out," says David Osborne of the Daviess Co. Detention Center.
To keep people safe, he says, requires a lot of eyes and some extra noses.
"These dogs don't seem threatening to me, but I'm sure they could be if under the right circumstances," says Osborne.
That's why area K-9 units are helping the Daviess County Detention Center, spotting drugs or weapons unseen by the naked eye.
"We're, particularly, experiencing a problem with a drug called Suboxone right now," he says. "They hide it under stickers, they hide it under postage stamps. So, we have to be very thorough and watch for that drug."
"It's best to keep all the drugs out of this place."
Deputy Russ Day of the Daviess County Sheriff's Department says it's a team effort. The K-9s see what humans can't and vice versa.
"It's up to the handlers, the human handlers, to look around the room while the dog is searching to find areas that we think an inmate may hide contraband," he says. "So, it's our responsibility to get our dogs to where that contraband might be hidden."
Nothing was found in Monday's sweep. But Osborne says it does keep inmates in line.
"No matter how many cameras, no matter how many deputy jailers we have here, we can always use the extra help," says Osborne. "Those noses are incredible."
Both Osborne and K-9 handlers say they would like to see these dogs used more often in the searches.
