William Stevenson, who was briefly married to former first lady Jill Biden more than five decades ago, has been charged with the murder of his longtime wife, Linda Stevenson, Delaware police announced Tuesday.

On Dec. 28, just before midnight, police responded to a domestic dispute at the Stevensons’ New Castle County home. Police said they found Linda Stevenson unresponsive in the living room, and after attempting “life-saving measures,” she was pronounced dead. Police provided few details of the incident and did not say how she died.

On Monday, authorities presented the case to a grand jury and an indictment was returned, charging the 77-year-old with first-degree murder. Police took him into custody “without incident” that same day. His bail was set at $500,000 cash.

William and Linda Stevenson had been married for about 40 years.

Linda Stevenson, 64, was a mother, grandmother and business owner.
