The Cook County medical examiner's officer revealed that trans activist Elise Malary died from drowning but that the manner of death could not be determined, The Chicago Sun-Times reported.
Malary's body was found in Lake Michigan in Evanston this past March.
Malary, a prominent transgender-rights and anti-racism activist, had been missing since March 9, Windy City Times reported. Her disappearance sparked widespread concern throughout her communities in both Evanston, where she lived, and Chicago, where she worked and was active in several organizations.
She uncharacteristically went out of contact with family on March 9, a day after reportedly quitting her job as a clerk with the Illinois attorney general's office.
The following day, maintenance personnel checked Malary's Evanston apartment, which was unlocked. Her car was gone but was found in a nearby municipal parking lot on March 14.
Autopsy results released June 12 ruled her death a drowning. However, the medical examiner's office was unable to rule if her death was accidental or not, the Sun-Times noted.
At this year's Andersonville Midsommarfest, there was a moment of silence honoring Malary.
Police have asked anyone with information about Malary's death to contact Evanston police detectives at 847-866-5040. Tips can also be texted to 274637, starting the message with EPDTIP.
