Jessica and Eric Ko-Dalzell said they purchased the Sammamish mansion Swift lost to foreclosure last year and the 27-year-old former NBA big man and some others finally vacated the home last weekend, the Seattle Post-Intelligencer reported Thursday.
"The first thing you get when you walk in the door is kind of whiff of whatever is festering in here," Jessica Ko-Dalzell said.
The couple said there was smashed glass in the fireplace, an El Camino with no engine in the driveway, animal feces on the deck, walls with holes on different levels of the house and trash piled on the kitchen floor.
The Dalzells said the basement was apparently used as a makeshift shooting range, with bullet marks on load-bearing arms, the online newspaper said. They said a handgun was found in the home.
