A Delaware man who was married to former first lady Jill Biden decades ago pleaded not guilty Tuesday to killing his second wife in Delaware. 

William Stevenson, 77, is charged with killing Linda Stevenson, 64, who was found unresponsive at their home in Wilmington on Dec. 28. 

He remains in custody on $2 million bail after being charged with murder on Feb. 3.

Linda Stevenson ran a bookkeeping business and was described in her obituary as a family-oriented mother and grandmother and a Philadelphia Eagles fan. The obituary does not mention her husband, despite them having been married for 40 years.

William Stevenson, founder of the popular Delaware music venue Stone Balloon, appeared remotely in court Tuesday. 

“The pain of losing her is paralyzing and the emptiness in my heart is an abyss,” Linda’s daughter, Christine Vettori, wrote in a Facebook post after her death. “Most days I can barely breathe.”

Stevenson married Jill Biden in 1970 when she was an 18-year-old University of Delaware student and he was 23. The nuptials lasted five years before they divorced. 

Stevenson remained a critic of his ex-wife, but said he wasn’t “bitter” about the way things ended. 

“I’m not bitter because, if it wasn’t for my divorce, I would never have met my wife Linda and she’s the greatest thing in my life,” Bill told the Daily Mail in a 2020 interview. 

Jill Biden went on to marry former President Joe Biden, who served in the White House from January 2021 to January 2025.
