Ian and Nicole Hockley lived across the street from Adam Lanza, but they never got to know him or his family before the 20-year-old gunman killed their young son and 25 other people inside Sandy Hook Elementary School.
In the weeks since the Dec. 14 shooting in Newtown, the couple said they have wondered whether more community involvement in Lanza's life might have prevented the bloodshed.
Coming together has been a popular theme at vigils and concerts held in tribute to the 26 people killed inside the schoolhouse. For some of the families who lost loved ones, a renewed focus on community would be a silver lining to the tragedy.
The parents of another shooting victim, Chase Kowalski, have started a foundation in the hope of building community centers in his honor.
