Chronicle<\/p>\n<p>A San Francisco jury found Lisa Gonzales guilty of the 2018 murder of her roommate, a long-awaited resolution to what District Attorney Brooke Jenkins called \u201cone of the most gruesome crimes our city has experienced in recent history.\u201d\u00a0<\/p>\n<p>Gonzales, 55, was convicted of second-degree murder last week, Jenkins announced Wednesday. During the nearly month-long trial, the jury heard testimony about the simmering tension between Gonzales and her roommate, 61-year-old Maggie\u00a0Mamer.\u00a0<\/p>\n<p>After noticing broken or misplaced items around the Mission District apartment, Gonzales allegedly began pressuring\u00a0Mamer to move out of the home they had shared since August 2017. Mamer, who was paying $400 in rent, stayed put. Gonzales complained about the dilemma to her coworkers, they suggested ways Mamer could legally be evicted.\u00a0<\/p>\n<p class=\"uiTextSmall f aic jcc\">Article continues below this ad<\/p>\n<p>\u201cNo thanks,\u201d Gonzales responded, according to the district attorney\u2019s office. \u201cI\u2019ll do it my way.\u201d\u00a0<\/p>\n<p>Gonzales grew up in the apartment and had protested her own attempted eviction four years earlier. In mid-April of 2018, she gave\u00a0Mamer a 30-day notice to move out, prosecutors said. When their third roommate came home from work on her lunch break on May 15, Gonzales told her not to go into the bathroom.\u00a0<\/p>\n<p>San Francisco Chronicle Logo<\/p>\n<p>Make us a Preferred Source to get more of our news when you search.<\/p>\n<p><a href=\"https:\/\/www.google.com\/preferences\/source?q=sfchronicle.com\" data-link=\"native\" role=\"button\" aria-label=\"Add Preferred Source\" class=\"td300 cp f aic jcc disabled:cd wsn px24 y40px px16 py8 buttonSm fs13 xs:fs16 xs:buttonLg bg-primaryAccessible hover:o80 c-white disabled:bg-gray300 disabled:c-gray600 border bn tac br2\"><\/p>\n<p>Add Preferred Source<\/p>\n<p><\/a><\/p>\n<p>That evening, the roommate noticed \u201ca metallic smell\u201d throughout the apartment and heard \u201csawing noises\u201d coming from the bathroom that went on for four hours, she told prosecutors. Gonzales was still in the bathroom the next morning. \u00a0When the roommate got home from work that night, the metallic smell had been replaced by that of vinegar and bleach, she said.\u00a0<\/p>\n<p>\u201cShe observed a hacksaw under the sink in the laundry room,\u201d prosecutors said. \u201cWhen she asked where the victim had gone, Ms. Gonzales replied that she had left, \u2018but not the way she wanted to.\u2019\u201d<\/p>\n<p class=\"uiTextSmall f aic jcc\">Article continues below this ad<\/p>\n<p>On June 1,\u00a0Mamer was reported missing by friends, who investigators said were concerned about her souring relationship with Gonzales. The next day, a \u201cconcerned citizen\u201d went to the police department to report a murder and dismemberment at a home on the 200 block of 14th Street, investigators said.\u00a0<\/p>\n<p>Officers from the San Francisco Police Department knocked on the door of the home and were welcomed inside by Gonzales, who said she lived there with one roommate and no one else.\u00a0<\/p>\n<p>\u201cShe also stated that the victim had once lived in the apartment but lied and claimed that she recently relocated to Eureka,\u201d prosecutors said. \u201cShe also told the officers that she helped the victim move out on May 15, 2018, and she had not seen her since.\u201d<\/p>\n<p>When officers searched the building\u2019s storage area, they found a blue plastic container that smelled of decay and was swarmed with maggots.\u00a0Mamer\u2019s decaying body was in a plastic bag inside, with her limbs cut off and stacked on top of her intact head and torso. Traces of her blood were later found in Gonzales\u2019 bathroom.<\/p>\n<p>An autopsy later found that\u00a0Mamer had died from \u201csharp force injuries\u201d to her head and heart. An allegation that Gonzales used a knife in the murder was also found true by the jury last week.\u00a0<\/p>\n<p class=\"uiTextSmall f aic jcc\">Article continues below this ad<\/p>\n<p>Gonzales was promptly arrested and pleaded not guilty to the crime. Jenkins, who handled the case during her time in the district attorney\u2019s office\u2019s homicide unit, said \u201cyears of delay from Gonzales\u201d stalled the trial until this February. Gonzales will next appear in court on April 24 to set her sentencing hearing. She faces 16 years to life in prison.<\/p>\n<p>\u201cThis was very gruesome,\u201d Jenkins said Wednesday. \u201cIt was very difficult to get through that testimony. But at the end of the day, this was about making sure that we held someone who is extremely violent and clearly very dangerous accountable.\u201d<br \/>\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"San Francisco District Attorney Brooke Jenkins announced today that her office has convicted Lisa Gonzales, 55, after a&hellip;\n","protected":false},"author":2,"featured_media":226049,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[30],"tags":[184,7,723,101,103,102,104,106,105,2013],"class_list":{"0":"post-247534","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-san-francisco","8":"tag-bay-area","9":"tag-california","10":"tag-crime","11":"tag-san-francisco","12":"tag-san-francisco-headlines","13":"tag-san-francisco-news","14":"tag-sf","15":"tag-sf-headlines","16":"tag-sf-news","17":"tag-us-and-world"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/247534","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=247534"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/247534\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/226049"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=247534"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=247534"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=247534"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
