Mark Deandre Grant III, a 29-year-old Black man, was living with his girlfriend, Jecenia Grant, in a drainage tunnel near Arville Street and Harmon Avenue in Las Vegas. The couple had been sheltering in the tunnel system for about seven and a half months and had made a life there.

In the early morning of February 20, 2023, police were called about an unresponsive man at approximately 2:40 a.m. Officers found Grant beside the drainage canal; medical personnel pronounced him dead at the scene. Investigators determined he had been shot inside the tunnel and, after being wounded, managed to exit the canal before collapsing nearby.

The investigation continued into April 2023, when police identified and arrested 34-year-old Jemiah Garner, who was already in custody on unrelated charges, in connection with the homicide. Garner was scheduled for arraignment on the new charges and was also facing a separate felony assault with a deadly weapon charge. Anyone with information about the shooting is asked to contact the LVMPD Homicide Section at 702-828-3521 or Crime Stoppers at 702-385-5555.

Did anyone in the Las Vegas tunnel community know Mark or see anything that night?
