“Neighbors told CBS 11 News that an older couple lives at the home that authorities are focused on. Some believe there was another person living there over the years, but they did not recognize Crusius when shown a picture of him.
....
CBS 11 also spoke to another man who said he knew Crusius from 2011 to 2013. He said there where no red flags or signs of turmoil during his time around the suspect. He also said he last heard that the 21-year-old was going to live with his grandparents.”
From my research, the house that was surrounded by atf etc is his grandparents (mom’s side) house.
