Lawmakers in Missouri are advancing new legislation that could significantly broaden the scope of DNA collection during arrests, a move supporters say may help solve crimes faster, prevent repeat offenses, and protect the innocent.
What Senate Bill 1458 Proposes
Under current Missouri law, DNA samples are collected only when individuals are arrested for specific violent felonies. However, Senate Bill 1458 aims to expand this authority, allowing law enforcement to collect DNA from individuals arrested for any felony offense.
State Senator Nick Schroer, one of the bill’s sponsors, said the proposal would create consistency in how DNA evidence is gathered and bring Missouri in line with practices already adopted in other states.
According to Schroer, the legislation would also align with legal standards established by the U.S. Supreme Court, which has previously upheld the constitutionality of DNA collection during arrests.
Supporters Say It Could Solve Crimes and Prevent Reoffending
Advocates argue that expanding DNA databases could play a crucial role in solving cold cases and deterring future crimes.
Ashley Spence, founder of the DNA Justice Project, has been a vocal supporter of the measure. Drawing from her personal experience as a survivor of sexual assault, she said earlier DNA collection could have helped identify her attacker sooner.
Supporters also point to research suggesting that individuals added to DNA databases are less likely to commit new crimes, as the likelihood of being identified increases.
Experts Highlight Role in Exonerating the Innocent
Policy experts say expanded DNA collection does more than aid investigations—it can also help clear wrongfully accused individuals.
Jennifer Doleac, a researcher with Arnold Ventures, noted that DNA databases can be critical in identifying the true perpetrators of crimes. This, in turn, strengthens cases for exoneration when wrongful convictions occur.
Safeguards and Privacy Considerations
Supporters emphasize that the bill includes protections for individuals who are not convicted. If a person is found not guilty, their DNA profile would be removed from the database and destroyed, addressing some privacy concerns.
Still, debates continue over civil liberties, with critics in broader discussions often raising questions about data privacy and the potential misuse of genetic information.
What Happens Next
The bill has already cleared a committee stage and is now headed to the legislative floor for further debate and voting.
If passed, Missouri would join a growing number of states that allow DNA collection for all felony arrests—potentially reshaping how law enforcement approaches criminal investigations across the state.
