It’s happened again, this time in Eerie, Pennsylvania. Police say a 45-year-old grandfather and father has killed his entire family along with a family friend. The details of this crime are horrific, with police describing a scene too gruesome to fully reveal. Video and audio evidence points to the man killing his 1 and 5 year old grandchildren, then four other family members on the stairwell, before being killing two women who were pounding on the front door and then ultimately himself. Officials are trying to determine motive, with neighbors and friends expressing disbelief, in this latest in a string of familicides in this country this year.
