Former presidential nominee Mitt Romney said his family is “heartbroken” after his sister-in-law, Carrie Elizabeth Romney, died in Valencia, California, on Friday at age 64.

Authorities found her body near a shopping mall parking garage, but it is currently unclear whether she jumped or fell from the multi-story structure.

Foul play does not appear to be involved, and the Los Angeles County Medical Examiner’s Office has listed her cause of death as “deferred” pending further investigation.

Carrie had recently separated from Romney’s brother, Scott Romney, who filed for divorce in June after eight years of marriage.

She had been seeking spousal support, which Scott opposed, and requested to resume using her maiden name, Carrie Elizabeth Dimas.

The couple married in 2016 and largely kept their relationship private.

Mitt Romney described Carrie as bringing “warmth and love to all our lives” and asked for privacy during this difficult time.

Scott Romney, 81, is an attorney in Michigan and has served on several corporate boards, the New York Post has reported.

Mitt Romney, who ran for president in 2012 and served as a U.S. senator from Utah, has been a prominent critic of former President Donald Trump and notably voted to convict Trump in both impeachment trials.
