Many Staten Island residents are still not back in their homes since Sandy washed ashore. Local volunteers have opened a toy store where FEMA-registered families with children can pick up donated toys, holiday decorations and stocking stuffers. Thus far, the shop has given away more than 2,000 toys.
Sandy Hook and other mass killings have left people wondering how someone could engage in such behavior. Scientists say that genes can indeed predispose a person to mental illness or violence. But genetic variants alone can't explain why someone commits mass murder.
