They both said they observed overgrown grass in the yard and piles of wet newspapers by the door. Kowalewitch, who lives on 24th Street a few blocks away, said he drove past Nygaard's unit around 40 times and never saw his car there. He looked in the windows and saw an inflatable mattress, "sort of in the middle of the living room." He also said he opened Nygaard's trash cans on his property, which he said were empty before the trash trucks had collected that day.
