Dionca Guess was 26 when she was found dead from a gunshot wound inside a vehicle in the 5700 block of North Garrison Avenue in Tulsa on the evening of December 28, 2018. The Tulsa Police Department’s investigation identified a suspect, and Keyon Sloth was arrested and charged with her murder. The case went to trial, a jury found Sloth guilty, and he was sentenced to prison.

Despite that conviction, members of Dionca’s family—including her cousin Erica Guess Hudson—have publicly stated they believe Sloth is innocent and are campaigning to have the conviction overturned. Their continued advocacy has kept questions about the case alive for the community.

If anyone knew Dionca or has information about the night she was killed, please share what you know.
