SF woman accused of killing, chopping up roommate Published on June 06, 2018 at 10:31AM by By Evan Sernoffsky Police officers thought they were doing a simple door-knock at a Mission District apartment to check on a San Francisco woman who recently went missing. But during their visit Saturday afternoon to the home on 14th Street, the officers made a disturbing discovery: A dismembered and decomposing body stuffed inside a plastic tub in a storage area under the apartment, two sources familiar with the investigation told The Chronicle. The missing woman’s roommate, 47-year-old Lisa Gonzales, was promptly arrested. On Tuesday, the district attorney’s office charged her with murder, and she is expected to appear in Superior Court as soon as Wednesday for arraignment.
