The wife of Jill Biden’s ex-husband, William Stevenson, had described him as a romantic in an interview about five years before he allegedly murdered her in December.
Stevenson, and his second wife, Linda, had spoken to "Delaware.
Officers were called on Dec. 28 concerning a domestic dispute to a home where they found Linda Stevenson unresponsive, authorities said at the time.
After being pronounced dead, her body was turned over to the Delaware Division of Forensic Science for an autopsy.
Authorities have not provided a cause of death as of Wednesday.
Linda Stevenson’s obituary states that she "passed away unexpectedly." It lists those she is survived by — a list that notably excludes her husband.
At the time the obituary was published, the missing detail caught the public’s attention, with a friend asking Stevenson on Facebook why that was the case.
"Bill, your wife's obituary is in the paper and you are not listed anywhere as her husband or your name is not listed," a woman wrote on Jan. 14, according to Joe Biden in 1977.
Jill Biden declined to comment on the matter through an emailed response from a spokesperson at the former president and first lady’s office, according to The Associated Press.
