"INDIANAPOLIS – A bill that would require all felony arrestees to submit a DNA sample is headed to the governor’s desk for his final decision.
Senate Bill 322 requires the sample to be taken by a cheek swab along with fingerprints, photographs during the arrest. The DNA will go to through a database, once the authorities have probable cause.
Sen. Brandt Hershman, R-Buck Creek, represents the people of Delphi, Indiana, and he said this type of technology could find the murderer of the two young girls from his district."

Subsequent news stories say Indiana Gov. Eric Holcomb signed the bill and it goes into effect July 1, 2017.
