Sheila Adhiambo Lumumba was a Kenyan hotel worker who was non-binary and lesbian. On 15 April 2022, Lumumba did not report to work, and co-workers who tried to reach them by phone received no response. Two days later, on 17 April 2022, Lumumba's body was discovered in their home. A post-mortem examination conducted at Karatina Sub-County Hospital determined that Lumumba had been sexually assaulted and stabbed multiple times. Lumumba's funeral service took place on 30 April 2022.
According to a report by openDemocracy on 20 July 2022, a man had been arrested and charged with murder in connection with the case, with a court hearing scheduled for 15 August 2022.
Lumumba's death prompted significant reaction from human rights organizations and LGBTIQ+ advocacy groups both within Kenya and internationally. The Kenyan National Gay & Lesbian Human Rights Commission described the murder as "part of a pattern of attacks and violence against LGBTIQ+ persons in the country." OutRight Action International characterized it as part of "a series of homophobic and transphobic attacks," warning that failure to respond effectively to such violence "sends the message that violence against LGBTIQ individuals can be carried out with impunity." The Kenya Human Rights Commission stated that "too many queer Kenyans are getting killed with no accountability for perpetrators."
Human Rights Watch called on the Kenyan government to repeal anti-LGBT+ laws and to incorporate LGBT+ people into national plans addressing gender-based violence, stating that Lumumba was "invisible under Kenya's current policies." In response to the killing, the Kisumu Feminists' Society launched a social media campaign under the hashtag #JusticeForSheila, aiming to raise public awareness of the case and to press police toward more effective investigation and action.
The case has been referenced alongside other instances of violence against LGBTIQ+ individuals in Kenya, including the case of Edwin Chiloba.
