San Francisco Woman Convicted in 2018 Murder Case

After nearly eight years, a San Francisco jury has found Lisa Gonzales guilty of murder in the death of her roommate, Margaret Mamer. The verdict was announced on Wednesday by the office of District Attorney Brooke Jenkins.

Details of the Crime

55-year-old Lisa Gonzales was convicted of second-degree murder for the killing of 61-year-old Margaret Mamer. Mamer’s remains were discovered by authorities on June 2, 2018, inside an apartment building in San Francisco’s Mission District.

Initial Investigation and Discovery

Margaret Mamer was reported missing on June 1, 2018, after friends grew concerned due to a lack of contact and reported escalating tension with Gonzales. Police visited Gonzales’ apartment on 14th Street the following day following a report of a potential murder.

During questioning, Gonzales told officers that Mamer had moved to Eureka and that she had assisted with the move the previous month. A search of a storage area revealed a blue container containing human remains, later identified as Margaret Mamer.

Evidence and Autopsy Findings

Crime scene investigators found the victim’s blood throughout the bathroom. An autopsy determined that Mamer died from multiple sharp force injuries. Prosecutors argued that Gonzales dismembered Mamer’s body in an attempt to conceal the crime.

Statement from the District Attorney

“The jury’s verdict delivers justice to the victim’s family and friends who continue to grieve and are still deeply impacted by this heinous murder,” stated District Attorney Brooke Jenkins. “After nearly eight years, this conviction demonstrates my office’s unwavering commitment to getting justice for victims and holding offenders accountable.”

Current Status

Gonzales remains in custody, and a sentencing date has not yet been scheduled.
