Supporters of a bill moving through the Montana Legislature say DNA crime scene evidence needs to be stored, for up to 30 years, to protect wrongfully convicted criminals, the measure would allow people convicted of murder or rape to request that the biological evidence from their cases be preserved for up to 30 years after conviction. State Senator Linda Moss.

Opposition to the measure, which has already passed the senate, says there is no need to hold the evidence for such a long period of time, when DNA evidence testing can be done immediately.
