Dequan Michael Sullivan was a 17-year-old from Thibodaux, Louisiana, who was killed by gunfire on Thursday, December 26, 2019. Known as Quan, he left behind his parents Monica Stepter Thompson and Derrick Sullivan, several siblings, and a young daughter, Avah Arielle Sullivan.

In March 2021 investigators arrested and charged three men with second-degree murder in connection with Sullivan’s death: 23-year-old Joshua Birdis, 19-year-old Brennan Mitchell Jr., and 20-year-old Wilfred Mitchell. Detectives found the three men already jailed in neighboring jurisdictions on unrelated homicide charges when the warrants were obtained, and they were transferred to the Lafourche Parish Correctional Complex to await trial. Authorities did not release a motive, citing pending court proceedings.

If anyone knew Quan, his family, or has information about the shooting on December 26, 2019, please share what you know.
