Some 4,000 convicted felons in Wisconsin have served their time, but their DNA is not included in the state DNA databank, the Milwaukee Journal Sentinel reports. The newspaper analyzed a database of more than 12,000 felons found missing from the DNA database last month after an audit by the state Justice Department. The DNA profiles of at least 400 registered sex offenders are unaccounted for. Samples were missing for hundreds of felons who committed violent crimes such as homicide, armed robbery, shooting, and beating, along with several thousand more who were busted for dealing drugs.
The state has said that about 12,000 samples that should be in the 128,605-sample DNA databank are not there. Problems with the databank were found during an investigation into suspected Milwaukee serial killer Walter Ellis. The audit was ordered after investigators found that Ellis’ DNA wasn’t in the databank. John Dipko of the Department of Corrections said the agency continues to fill the DNA holes on the collection side with a priority on those still under supervision
