The father of the man sources say killed 26 at a Connecticut school before taking his own life learned of his son's likely involvement from a reporter outside his home.
Police had just left Peter Lanza's Stamford, Conn., home after conducting a welfare check when Lanza drove up in his Mini Cooper, according to Hearst Connecticut Media.
"Is there something I can do for you?" he said.
When the reporter told Lanza his address had been linked to the shooting in Newtown, Conn., on the other side of Fairfield County, he "took the news as a blow -- his face turning from patient to surprised and horrified" before declining to comment, rolling up his window and driving into the garage, according to the Hearst Connecticut report.
Lanza's 20-year-old son, Adam Lanza, has been identified by sources as the gunman who opened fire Friday morning at Sandy Hook Elementary School, killing 20 children and six adults before taking his own life.
Sources say Lanza earlier killed his mother, Nancy Lanza, a teacher at the school, with a shot to the head at their Newtown home, then drove her car to the school to carry out the rampage.
Peter and Nancy Lanza divorced in 2008, according to Hearst Connecticut. Peter Lanza reportedly works as vice president of taxes for GE Energy Financial Services.
