Tierra Hallman, 28, was last seen on October 15, 2021, in Riverside, California. Before she disappeared Tierra had been dealing with legal troubles and substance abuse, and family members say her contact with them had grown increasingly sparse in the weeks before she was last heard from.

Family-organized searches and a GoFundMe were set up to support efforts to find her, but those efforts have not produced significant leads. Authorities describe the investigation as ongoing and are asking anyone with information, however small, to come forward. The exact circumstances of her last known whereabouts remain unclear.

If anyone knew Tierra’s routines, recent contacts, or saw her in Riverside around October 15, 2021, please share what you remember.
