Veteran American actor Stacy Keach, widely recognised for his performances in Mike Hammer, Prison Break and Blue Bloods, has died at the age of 85. His wife, Malgosia Tomassi Keach, confirmed that the acclaimed performer passed away at their family home in Magdalenka, Poland, following a prolonged battle with a serious heart condition and heart failure. Her emotional statement has brought renewed attention to their marriage, which lasted four decades.

Keach married Polish actress and model Malgosia Tomassi in June 1986, and the couple remained together throughout the remainder of his life. Their relationship was one of the longest-lasting marriages in his personal history, and they raised two children, Shannon and Karolina. Although Keach spent much of his career in the public eye, his family remained an important part of his life away from Hollywood.

Tomassi worked in entertainment during the 1980s and became associated with the television productions that helped establish Keach as a familiar face among crime drama viewers.

While her husband continued building an extensive career across television, film and theatre, Tomassi gradually stepped away from the public spotlight.

She maintained a relatively private lifestyle, focusing on family responsibilities and supporting Keach through different stages of his professional and personal life.
