Katherine Urbanek, 62, was last seen on June 17, 2021, in Fontana, California. Her disappearance prompted a joint investigation by Fontana and Rialto police that included a search of a Fontana home’s backyard, where human remains were found. Forensic testing was required to determine whether the remains were Katherine’s. Authorities say the discovery and surrounding circumstances have led them to suspect foul play, and the investigation remains active as police seek information to clarify what happened.

If anyone in Fontana or Rialto recalls Katherine, saw her on or after June 17, 2021, or has information about the backyard search, please come forward to investigators.
