Jill Biden’s first husband pleads not guilty to murdering second wife

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.
