Police found the six family members dead in the home. A mass killing where two siblings are the perpetrators is rare, said James Alan Fox, a criminologist at Northeastern University. The Associated Press/USA Today/Northeastern University Mass Killing Database has recorded 452 incidents of mass killings — the slaying of four or more people — from 2006 through Sunday, he said. He said that of the 217 family mass killings, 207 involved a single perpetrator. The only other family mass killing recorded in the database that involved siblings was a 2015 slaying in Oklahoma.
