The Associated PressDENVER - A woman accused of cutting into the belly of an expectant mother to claim the unborn child can't be charged under Colorado law with murder. But Republicans in the state Senate advanced a bill Wednesday aimed at changing that situation. Republicans have drafted a proposal that would make killing a fetus a homicide in certain cases, setting up a debate over whether the measure will interfere with abortion rights. The GOP-led Senate Judiciary Committee, which considered the proposal, gave initial approval to it on a 3-2 party-line vote, sending to the full chamber for consideration.
