we've been trying to find out more about the 20-year-old suspect in this shooting and right now abc's chief investigative correspondent brian ross is back with what he knows at this hour. Reporter: As you know, this all took place in the small town of newtown, connecticut, a place where everything is nearby. The spree ended at the elementary school, but began at the lanza family home. Authorities identified the shooter at 20-year-old adam lanza. Seen here in a picture taken seven years ago and provided to abc news by a family friend who told us adam was obviously not well. Something we also heard from a newtown real estate agent, barbara frey, a family friend. He was not connected with the other kids. My son played with him when they were young. And in her home, I know she was very particular. I just think she maybe had too high a standard or something, or focused too much, for whatever reason. So was there conflict or tension between the two of them? The parent and child? Yes. Not that I know of, but the fact that the parents were divorced must have contributed. The mother was the first to die according to police. Adam's father and brother are being questioned by authorities where they live.
