Doris Gleason, a 92-year-old white woman, was murdered in her senior living apartment in Dallas, Texas, on October 29, 2016. Her death was first believed to be from natural causes, but investigators later determined it was a homicide. The apartment scene had been staged to look like she had fallen, and jewelry — including a guardian angel charm — plus cash were missing, which concerned her family.

Doris’s daughter, Shannon Dion, suspected foul play from the start. The investigation later connected her death to a pattern involving a man accused of targeting elderly women in the Dallas area; that suspect reportedly gained access by posing as maintenance or a caregiver, then smothered victims and stole valuables. The case has prompted calls from families for better protections for seniors in assisted living.

If anyone knew Doris, saw someone posing as maintenance at her complex, or has information about missing jewelry, please come forward.
