Lisa Gonzales, 55, was found guilty of second-degree murder following a jury trial, prosecutors announced Wednesday.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">\u201cThis is one of the most gruesome crimes our city has experienced in recent history,\u201d District Attorney Brooke Jenkins said.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">A third roommate said that in mid-April of 2018, Gonzales gave the victim 30 days\u2019 notice to move out, according to the district attorney\u2019s office. Gonzales complained to coworkers that her unwanted roommate was failing to leave, prosecutors said. When told of the various ways she could legally evict her, Gonzales responded, \u201cNo thanks, I\u2019ll do it my way,\u201d according to prosecutors.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The victim, 61-year-old\u00a0Maggie Mamer, was reported missing on June 1, 2018, by friends who had not heard from her for several days. The friends were concerned because of <a href=\"https:\/\/www.kron4.com\/news\/san-francisco-woman-accused-of-dismembering-roommate-appears-in-court\/\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"slk:escalating tension between the victim and her roommate;elm:context_link;itc:0;sec:content-canvas\" data-yga=\"{&quot;yLinkElement&quot;:&quot;context_link&quot;,&quot;yModuleName&quot;:&quot;content-canvas&quot;,&quot;yLinkText&quot;:&quot;escalating tension between the victim and her roommate&quot;}\" class=\"link \">escalating tension between the victim and her roommate<\/a>, Gonzales.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">On June 2, 2018, another concerned citizen went to the San Francisco Police Department to report that a grisly murder happened at a residence on 14th\u00a0Street, and a body was hidden in a basement storage area.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">When SFPD officers arrived at the home, Gonzales invited them inside.<\/p>\n<p><img alt=\"The home where a San Francisco roommate was murdered is shown in 2018.

(KRON4 Photo)<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">\u201cAs they all sat in the kitchen, Ms. Gonzalez told them that she lived in the unit with (one) roommate and no one else. She also stated that the victim had once lived in the apartment, but lied and claimed that she recently relocated to Eureka. She also told the officers that she helped the victim move out on May 15, 2018, and she had not seen her since,\u201d the district attorney\u2019s office wrote.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Officers then searched the apartment building\u2019s storage area and found a blue container with Mamer\u2019s dismembered body parts hidden inside.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The SFPD Crime Scene Investigation Team processed the bathroom for evidence and located the victim\u2019s blood spatter all over the scene, prosecutors said.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The third roommate told investigators that when she returned home from work on May 15, 2018, she noticed a metallic smell in the apartment.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">\u201cShe heard sawing noises coming from the bathroom, which lasted for four hours.\u00a0The next morning, Ms. Gonzales was still in the bathroom. When the third roommate got home that night, the bathroom door was open, and the apartment smelled of vinegar and bleach. She also noticed that the blue container that once held her dirty clothes was missing, and she observed a hacksaw under the sink in the laundry room. When she asked where the victim had gone, Ms. Gonzales replied that she had left, \u2018but not the way she wanted to,&#8217;\u201d the DA\u2019s office wrote.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Mamer\u2019s body remained in the blue container until June 2, 2018, when SFPD officers searched the home, prosecutors said.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\"><a class=\"link  yahoo-link\" href=\"https:\/\/www.yahoo.com\/news\/articles\/mom-slain-sunnyvale-illegal-aliens-195127485.html\" data-ylk=\"slk:Mom was slain in Sunnyvale by \u2018illegal aliens\u2019 protected from ICE, DHS says;elm:context_link;itc:0;sec:content-canvas;outcm:mb_qualified_link;_E:mb_qualified_link;ct:story;\" data-yga=\"{&quot;yLinkElement&quot;:&quot;context_link&quot;,&quot;yModuleName&quot;:&quot;content-canvas&quot;,&quot;yLinkText&quot;:&quot;Mom was slain in Sunnyvale by \u2018illegal aliens\u2019 protected from ICE, DHS says&quot;}\" rel=\"nofollow noopener\" target=\"_blank\"> Mom was slain in Sunnyvale by \u2018illegal aliens\u2019 protected from ICE, DHS says <\/a><\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">An autopsy revealed the victim died as a result of multiple sharp force injuries to her head and heart, including on her face and skull.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">\u201cThis was a deeply disturbing and heartbreaking case, and I want to thank the jurors for their careful attention to the difficult evidence and their commitment to justice,\u201d said Assistant District Attorney Melissa Demetral. \u201cWhile no verdict can undo this horrific act, we hope this conviction brings a measure of closure and accountability.\u201d<\/p>\n<p><img alt=\"Brooke Jenkins\" loading=\"lazy\" width=\"900\" height=\"599\" decoding=\"async\" data-nimg=\"1\" class=\"rounded-lg\" style=\"color:transparent\" src=\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2026\/04\/9c348e7155ba675ca0ef77826f654440.jpeg\"\/><\/p>\n<p>District Attorney Brooke Jenkins speaks during the launch of Domestic Violence Awareness Month at the City Hall on October 24, 2023.
