Who holds someone arrested in Knox County?
Usually Knox County Jail / Sheriff, (309) 345-3742. The arresting agency books the person and the jail holds them; ask the jail what holds are on the booking before you act on anything.
Does posting bond mean the person comes home?
Not always. A probation or parole hold, another county\'s warrant, or an immigration detainer can keep someone in custody after bond is posted. Ask the jail what holds are on the booking, and ask the bondsman what happens if there are, before you pay.
What should I confirm before visiting?
Confirm the person\'s current facility, the visiting schedule, approval requirements, accepted identification and arrival instructions. Check the facility guide before you travel.
What if I find something that needs correcting?
Send us the page and the detail that needs attention. Do not send private booking documents or other sensitive personal information.
