UPDATE 6:30 p.m.: Originally it was thought that Adam Lanza, the gunman, shot his mother at the Sandy Hook Elementary school, where she was a teacher's aide. ABC has learned that, in fact, Nancy Lanza was killed at her home (by her son) prior to the massacre. He then drove to the school, where he killed 20 children and six adults, before killing himself.
A man drove from Long Island, New York, into Lower Manhattan earlier today in a van he thought was filled with explosives. He parked the van close to the Federal Reserve building, just a few blocks from the World Trade Center, and planned to detonate it using a cell phone from a nearby hotel.
The explosives, however, were fake.
Things kicked off around 9 p.m. Eastern in Danville, Kentucky, on the campus of Centre College, with Vice President Joe Biden and Congressman Paul Ryan meeting for their one and only debate during this election campaign
