Transit police in Boston are investigating a shooting on a subway platform near Harvard University that prompted the school to issue a shelter-in-place order.

For the boundaries of who’s responsible for a mass school shooting to continue to be pushed, prosecutors would have to consider a number of critical questions to determine whether to hold the Florida State University school shooter’s mother accountable for her son’s actions.

Police say the shooting suspect is the son of a respected local sheriff's deputy with strong ties to the community. He was shot and wounded at the scene.
