MADISON (WSAU)  Police and sheriff’s officers in Dane County conducted their first “D-N-A sweep” yesterday. They were looking for 93 convicted felons and sex offenders who never provided their D-N-A to authorities as required by law. And they found 14 of those offenders – including one who was wanted on an outstanding warrant.

About 30 officers took part in yesterday’s sweep. They included Dane County deputies, and police officers from Madison, Middleton, Fitchburg, and Sun Prairie.

The state began requiring D-N-A samples from convicted felons in 2000 for a statewide database that’s been heavily used in investigating past-and-present crimes. Later in the decade, it was discovered that 12,000 convicts never provided their required D-N-A samples – and authorities have made numerous efforts which has reduced the backlog.
