Michigan prison inmates will have to submit to DNA testing soon after they're locked up rather than waiting until just before they're released under a bill signed into law by Gov. Rick Snyder.
The state began collecting inmates' DNA samples in 1994, but inmates currently aren't required to provide a sample until they're released on parole, placed in a halfway house or discharged after serving their full sentences.
Supporters say the new law Snyder signed Thursday will help police solve cold cases sooner by giving them the ability to match inmates' DNA to unsolved crimes while they're still in prison.
Prison inmates now will have to give a DNA sample within three months of incarceration.
