William Stevenson, 77, of Wilmington was married to Jill Biden from 1970 to 1975.
Caroline Harrison, the Delaware Attorney General’s spokesperson, confirmed in a phone call that Stevenson is the former husband of Jill Biden.
Jill Biden declined to comment, according to an emailed response from a spokesperson at the former president and first lady’s office.
Stevenson remains in jail after failing to post $500,000 bail after his arrest Monday on first-degree murder charges. He is charged with killing Linda Stevenson, 64, on Dec. 28.
Police were called to the home for a reported domestic dispute after 11 p.m. and found a woman unresponsive in the living room, according to a prior news release. Life-saving measures were unsuccessful.
She ran a bookkeeping business and was described as a family-oriented mother and grandmother and a Philadelphia Eagles fan, according to her obituary, which does not mention her husband.
Stevenson was charged in a grand jury indictment after a weekslong investigation by detectives in the Delaware Department of Justice.
