A Chico woman pleads no contest to voluntary manslaughter for stabbing a woman last year. 31-year-old Renee Mollison made the plea Wednesday. The E-R reports 53-year-old Diana Luke let Mollison into her apartment last year for a glass of water. That's when Luke's husband heard her screaming and found Mollison standing over Luke with a knife. The defense said it was planning to argue voluntary manslaughter, which can be committed during a sudden quarrel, the heat of passion or in imperfect self-defense. Mollison is looking at 12 years behind bars.
