EVANSVILLE, Ind. (AP) — Indiana is proposing a bill that would allow it to join at least 30 states already authorizing analysis of DNA collected from people arrested for felonies.

The Evansville Courier and Press reports the bill would allow DNA samples collected after June 30, 2017, to be uploaded to the existing database. Vanderburgh County prosecutor Nicholas Hermann says DNA is useful in investigating and prosecuting cases and that the bill will help Indiana catch up technologically.

The current draft of the proposal would let people request their DNA be expunged from the database if they were acquitted after being arrested for a felony.

State Sen. Erin Houchin, a sponsor of similar legislation, said Indiana already collects DNA after conviction, and that the state has been collecting fingerprints for years.
