Loudoun County investigators are trying to figure out how a woman ended up dead in her own home. Saturday morning, a man called a family member to come over and take care of his children.

A short time later, the man got into a serious head-on crash in the area of Gum Spring Road and Mayhew Lane. When family members got to his home on Gayfeather Drive shortly before 8:15 a.m. in the Dawson's Corner neighborhood in Chantilly, they found the dead body of the man's wife.
