Middleton, Md ? An accountant for a railroad operator 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.

Authorities didn’t specify a motive but said there was evidence the man faced psychiatric and financial problems.

When investigators arrived at the two-story home, 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, 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” and each also had at least one gunshot wound from a .25-caliber handgun, Frederick County Sheriff Charles Jenkins said. Their precise cause of death wasn’t immediately known, and Jenkins declined to say what was used to slash them.

The sheriff also said there was evidence that Wood, a sales accountant at CSX Corp., faced financial problems and may have been in debt.

CSX did not immediately return a phone call seeking comment Saturday.
