No Easy Answers for Lanza's Motives for Shooting

Family divorce and autism disorder known, but no signs of violent behavior

When the parents of Adam Lanza divorced, the settlement left Nancy Lanza with $24,150 a month in alimony payments and able to live a comfortable life to care for her son.

Nancy Lanza, 52, was her son's first victim on Friday, shot to death in the spacious home they shared, authorities said. Adam then took his mother's car and some of her guns, went to the Sandy Hook Elementary School, where he forcefully entered the building and opened fire, killing 20 children and six adults before turning a gun on himself.

Funeral services for the children, whose murders wrenched the nation's heart, began on Monday.
