the media is already contradicting themselves saying it was somebody in the home, and then tape off the entire block??? : "police said the violence was confined to the home."

Police said they have not yet made an arrest."- from Wtop - http://wtop.com/prince-georges-county/2017/08/bodies-3-children-found-clinton-home-police-investigate-homicide/slide/1/
