Third Death Linked to US School Shootings Raises Questions

Suicides of three people linked to mass school shootings in the U.S. in just over a week prompt questions if one suicide may have inspired the others. Two students from a Florida high school where a gunman killed 17 students last year took their lives within a week of each other this month, and the death of the father of one of 20 children killed in an elementary school shooting in Connecticut followed.
