HELENA, Mont. (AP) — The wife of a Montana man who died in custody says a Shelby prison's staff refused him medical treatment because he was a temporary inmate awaiting a transfer to a federal medical facility.

Sherry Flor is suing Crossroads Correctional Facility owner Corrections Corporation of America. She is accusing prison staff of negligence that led to 68-year-old Richard Flor's death in 2012.

The Flors and their son pleaded guilty to drug charges related to a medical marijuana operation run out of their Miles City home. Richard Flor spent about four months in the Shelby prison and died in a Las Vegas jail during a layover in his transfer.

Attorney Brad Arndorfer says Flor had cancer that was undiagnosed and untreated.

CCA spokesman Steve Owen says Crossroads officials are committed to their inmates' health and safety.
