MO HB619

Allows death-sentenced individuals to file DNA testing motions if testing could demonstrate innocence regarding aggravating factors, even if they cannot claim innocence of the murder itself.

Modifies sentencing for first degree murder: persons 18+ who directly caused death, directed another, or agreed to the murder face death or life without parole; persons under 18 face life with 25-year minimum; accomplices 18+ face life without parole.

Removes "serious assaultive criminal convictions" as an aggravating circumstance and adds new aggravating factors: government attack, interference with criminal investigations, and murders of multiple victims.

Requires courts to instruct juries on any specific mitigating circumstances offered by defendants that are supported by evidence, regardless of statutory listing.

Eliminates the requirement that identity be an issue at trial for DNA testing eligibility and allows courts to order life without parole sentences for those convicted on aggravating factors later disproven by DNA evidence.
