Suzanne Crough, the youngest star of 1970s sitcom The Partridge Family, has died at the age of 52, TMZ reports.
Crough, who played Tracy Partridge, died suddenly at her home in Nevada. It is still unclear what caused her death.
Married with two daughters, she last reunited with her Partridge co-stars, including pop singer David Cassidy, for an appearance on a TV chat show in 2010.
Cassidy told TMZ: 'Although we did not know each other very well due to our age difference during our Partridge days, I always thought fondly of Suzanne and her family.'
