Roughly 2,000 convicted juvenile murderers could soon be free; the Supreme Court ruled Monday to retroactively apply its 2012 decision banning automatic life-without-parole sentences for minors. The 6-3 ruling in the case of Henry Montgomery, a Louisiana man serving time for killing a sheriff’s deputy as a 17-year-old in 1963, could see Montgomery and other convicted murderers become eligible for parole or receive a new sentencing hearing.
