Mercedes Clement, 25, was last seen in Dallas on October 11, 2020, on surveillance walking across the Koko Apartment Complex off Harry Hines Boulevard with a man and entering an apartment. That night friends later said her voice sounded fearful; she phoned at least one friend and said she needed a ride to her car, then the calls stopped. The next day her family learned her car had been towed; when her mother retrieved it personal items, including the purse seen on the surveillance video, remained inside.

Investigators found a long gap in the apartment complex surveillance overnight when recordings stopped. Police identified the man last seen with her as Tanner Losson and described him as a person of interest while continuing to look into others connected to her life, including people linked to a reported period of drug use. On February 13, 2022, skeletal remains were found near Lavon Lake; dental comparison later identified the remains as Mercedes Clement, and authorities said the inquiry was continuing as a homicide investigation. No cause of death or criminal charges had been publicly announced at the time of that identification; a reward was being offered for information leading to an arrest and indictment.

Did anyone living in or near the Koko Apartment Complex in October 2020 notice unusual activity or see Mercedes with someone that night?
