Marquell Gardner was 36 and a LaPlace, Louisiana resident and father of four when he disappeared on Halloween night, October 31, 2016. Known to friends and family as Que, Bigg Dogg, or Madd Dogg, he worked as a self-employed tattoo artist. He was last seen leaving his girlfriend’s home with an unidentified man who was driving a silver Buick with tinted windows.

On Sunday, November 6, 2016, a passerby found a decomposed body in tall grass in the 900 block of Napoleon Street in Baton Rouge, near the former Baton Rouge Police headquarters. The next day authorities publicly identified the body as Gardner’s and reported he had sustained multiple gunshot wounds. Investigators said it was unclear whether he was killed at that location or moved there afterward.

The Baton Rouge Police Department and the St. John the Baptist Parish Sheriff’s Office opened a homicide investigation and sought the unknown man and the silver Buick. No suspects have been publicly identified and no arrests have been announced; the motive remains unknown. Does anyone have information about Gardner, the man he left with, or that silver Buick?
