An Oregon woman accused of murdering a pregnant woman from Maryland and cutting the unborn child from her womb has pleaded guilty to a charge of aggravated murder and benn sentenced to life in prison. The sentence prohibits parole for Korena Roberts. The battered body of 21-year-old Heather Snively was found in the crawl space of Roberts' home in June 2009 after Roberts' boyfriend called 911. Prosecutors say Roberts bludgeoned Snively in the bathroom with a collapsible police baton, then used a sharp instrument to cut the unborn baby from Snively's abdomen. The baby was due a month later. For months before the killing, Roberts told neighbors was she was pregnant, going so far as to acquire a stroller, baby formula and parenting magazines.
