From the article:

The TV and film icon’s estate was awarded $13 million as a result of a wrongful death lawsuit against Gila Medical Center in Silver City, New Mexico, where Nichols was treated in 2022.

Local station KOAT 7 reported the actress had a heart condition, and during a visit to the ER … she allegedly did not get the proper treatment – and was transferred to an assisted living facility, where she died hours later. She was 89.
