Couple, their 3 children found dead in US home

A father killed his wife and their three children before fatally shooting himself in a northwest Maryland home, leaving a gruesome scene that was discovered Saturday by the youngsters' grandfather, authorities said. When investigators arrived, the couple's two sons, ages 5 and 4, lay dead in their beds, while the bodies of a 2-year-old daughter and the mother, Francis Billotti Wood, were in the master bedroom of the two-story home, Frederick County sheriff's office spokeswoman Jennifer Bailey said. On the master bedroom floor by the foot of the bed was the father, 34-year-old Christopher Alan Wood, dead of a self-inflicted gunshot wound, Bailey said. The 33-year-old mother and three children suffered "traumatic cuts," Bailey said, but the causes of their deaths weren't immediately confirmed.
