Georgia father’s conviction tests new frontier in school shooting cases

Experts say prosecutions of parents could reshape accountability for mass shootings in the US

In early March a Georgia man was convicted of murder nearly two years after his 14-year-old son allegedly shot and killed two students, two teachers and injured nine others. Though Colin Gray, 54, didn't fire any shots and wasn't at the school during the shooting, he was punished as such.

Gray's case marked the second time the parent of a school shooter in the US has faced a homicide charge, and legal experts say that it won't be the last. It's a development both the legal and gun violence prevention fields are watching closely. Will US prosecutors, desperate to stem the number of high-profile mass shootings, cast an ever wider net of responsibility?
