The state's online database has photos of most registered sex offenders living in Whiteside and Lee counties, but Sauk Valley Media discovered recently that a dozen were missing.
Since then, local police agencies have posted seven of them.
Whiteside County's section on the database has 124 offenders, while less populous Lee County had 73.
Illinois requires registered sex offenders to have their photos on the state's database.
According to the state police website, local law enforcement agencies must take photos of offenders in their jurisdictions when they register, then forward the pictures to state police.
On Feb. 22, Sauk Valley Media reported that six Lee County offenders had no photos on the website – three in Dixon, one in Ashton, and two in the unincorporated part of the county, which is the jurisdiction of the sheriff's department.
Only one photo – of an offender from Dixon – is still missing.
For the previous story, Dixon Police Chief Danny Langloss said the offender got his photo taken a day before Sauk Valley Media called. It was then sent to state police, he said.
Asked about it Wednesday, Langloss said his department sent the photo to state police the day the offender registered and the day Sauk Valley Media called.
"The state police has over 3,000 offenders," Langloss said in an email. "They have three people who man their office and one unpaid intern who reads all emails coming in."
In Whiteside County, six offenders' photos were missing on the website – two in Sterling and one each in Fulton, Prophetstown, Morrison and the unincorporated part of the county.
One of those from Sterling has moved to Wisconsin, where his photo is posted online. The other is considered noncompliant, meaning he failed to maintain accurate registration records as required by law, according to the website.
Two other Whiteside County offenders' photos are missing – one in Morrison and the other in the unincorporated area near Rock Falls.
Morrison Police Chief Brian Melton said the Whiteside County Sheriff's Department is handling the photo for the offender inside city limits.
"The sheriff's department was sending that photo to state police," Melton said. "The state police are backlogged; it'll be a matter of time before they post the photo."
The sheriff's department couldn't be reached for comment on the offender near Rock Falls.
Other counties also have missing sex offender photos on the state website. Of 204 offenders in LaSalle County, 16 photos are missing. In DeKalb County, six of 77 are not on the site.
State police provide an online listing of sex offenders who are required to register in the state of Illinois. The agency says it updates the database daily. The site allows searching by name, city, county, ZIP code, compliance status, or any combination thereof.
