Mass shootings are defined as cases in which four or more victims are shot whether fatally or non-fatally. The US’s perennially high numbers of mass shootings have prompted calls from lawmakers and advocates for more substantial federal gun control. But Congress has not implemented such restrictions. Authorities in Grand Haven had earlier said they were not looking for any suspects from outside the Karolkiewicz home after discovering the massacre. The names of the children slain had not been released as of Tuesday. “The investigation at this point shows that this was a murder-suicide , with the fire being started after the
