Katherine was the adopted daughter of the actor, 75, and his late wife, Nancy Dolman, who died from cancer in 2010.

Short and Dolman, who were wed for 30 years, also adopted sons Oliver Patrick, 39, and Henry Hayter, 36, together.

Then, in 2010, she earned her master’s degree in social work from the University of Southern California.

The businesswoman worked as a social worker for a private practice and part-time at the Amae Health clinic, an outreach group that provides psychotherapy, leading up to her death.

Additionally, Katherine was involved with Bring Change 2 Mind, a charity that strives to reduce the stigma surrounding mental health.
